If a doctor or audiologist has recommended a PTA test, or if you have simply noticed you are asking people to repeat themselves more often, you are probably looking for two things: a plain explanation of what this test actually involves, and a realistic sense of what it costs in Islamabad. This guide covers both, along with what your results actually mean once you have them in hand.

What Is a PTA Test

PTA stands for Pure Tone Audiometry, and it is the standard first test used almost everywhere in the world to measure hearing sensitivity. Rather than a general impression of whether you “hear well” or not, PTA measures the exact quietest sound you can detect at a range of specific pitches, from low frequencies around 250 Hz up to high frequencies around 8000 Hz. The result is plotted on a chart called an audiogram, which shows an audiologist precisely how much hearing loss you have, at which pitches, and in which ear.

PTA is considered the reference standard hearing test globally. According to the National Institute on Deafness and Other Communication Disorders, pure tone testing is the most common type of hearing evaluation used to find the quietest sounds a person can hear at different pitches, and it forms the basis for almost every hearing related decision that follows, including whether hearing aids are needed and how they should be programmed.

Why the Test Uses Two Types of Sound Conduction

A full PTA test typically measures hearing in two ways, and understanding the difference explains a lot about what your results will show.

Air conduction testing measures how sound travels through the ear canal, eardrum, and middle ear bones before reaching the inner ear. This is tested using headphones or insert earphones and reflects your overall hearing ability through the entire hearing pathway.

Bone conduction testing measures how sound travels directly to the inner ear through vibration, bypassing the outer and middle ear entirely. This is tested using a small vibrating device placed behind the ear on the mastoid bone.

Comparing the results of both tests is what allows an audiologist to determine the type of hearing loss you have, not just how much of it there is. If air conduction results are worse than bone conduction results, that typically points to a conductive problem, something blocking or restricting sound in the outer or middle ear, such as wax buildup, fluid, or an eardrum issue. If both air and bone conduction results are similarly reduced, that typically points to a sensorineural issue, meaning the inner ear or hearing nerve itself is affected. This distinction matters enormously for treatment, since a conductive problem is often medically treatable, while a sensorineural loss is usually managed with hearing aids.

At IHC, this combined air and bone conduction procedure is also listed separately as Audiometry (AC, BC) on our services page, since it is the specific clinical procedure that produces your PTA results.

Who Actually Needs a PTA Test

A PTA test is appropriate for a wide range of situations, not just for people who suspect significant hearing loss:

Anyone noticing early signs of hearing difficulty, such as frequently asking people to repeat themselves, turning the television volume higher than others prefer, or struggling to follow conversations in noisy places. Our guide on 10 early signs of hearing loss you should never ignore covers these signals in more detail.

Adults over 40, since age related hearing decline is gradual and often goes unnoticed until it has progressed. We cover this specifically in why hearing tests are essential for adults over 40.

People regularly exposed to loud environments, including factory work, construction, traffic noise, or frequent headphone use at high volume, since noise exposure is one of the most common preventable causes of hearing loss worldwide.

Anyone being fitted for hearing aids, since PTA results are what an audiologist uses to determine the correct amplification level for your specific hearing loss, at each frequency, in each ear.

Anyone monitoring an existing hearing condition, since repeat PTA testing over time shows whether hearing has stayed stable, improved, or declined.

How the PTA Test Actually Works

The process itself is simple, painless, and generally takes well under an hour for both ears.

1. You enter a quiet, sound treated room. This controlled environment ensures that background noise does not interfere with your results, since PTA measures extremely quiet sound thresholds.

2. Headphones or insert earphones are placed on or in your ears. Each ear is tested separately, one at a time, so results are ear specific rather than a combined impression.

3. Tones are played at different pitches and volumes. You will hear a series of beeping or steady tones, starting at a level you can clearly hear and gradually decreasing in volume until you can no longer detect it.

4. You respond each time you hear a tone, typically by raising your hand or pressing a button. Your responses at each pitch determine your hearing threshold, the quietest level at which you can reliably detect sound at that specific frequency.

5. The bone conduction portion follows, using a small device placed behind your ear rather than headphones, to test how sound travels directly through bone to the inner ear.

6. Your results are plotted on an audiogram, a graph your audiologist will walk you through, showing your hearing thresholds across the full frequency range for each ear.

What Your PTA Results Actually Mean

Once your audiogram is complete, your audiologist will explain where your results fall relative to standard hearing categories. According to the World Health Organization’s fact sheet on deafness and hearing loss, disabling hearing loss is generally defined as hearing loss greater than 35 decibels in the better hearing ear for adults, with categories ranging from normal hearing through mild, moderate, severe, and profound hearing loss depending on the degree of threshold shift measured.

What matters most is not memorizing these categories yourself, but understanding that your specific results, at your specific frequencies, determine what happens next, whether that is simply monitoring, medical referral for a treatable conductive issue, or moving forward with hearing aid fitting.

PTA Test vs Other Hearing Tests at IHC

It is common to see several different test names listed and wonder which one you actually need. Here is how PTA compares to some of the other tests we offer:

PTA vs BERA Test. PTA is a behavioral test, meaning it requires you to actively respond when you hear a tone, which makes it suitable for cooperative adults and older children. BERA (Brainstem Evoked Response Audiometry) is an objective test that does not require a behavioral response, which makes it the appropriate choice for infants, young children, or anyone unable to reliably participate in a behavioral test. Our BERA test guide covers this test and its cost in detail if a BERA has been recommended instead.

PTA vs Tympanometry. Tympanometry does not measure hearing sensitivity at all. It measures how well your eardrum and middle ear are functioning mechanically, which helps identify issues like fluid buildup or eardrum stiffness that PTA alone would not fully explain.

PTA vs Otoacoustic Emissions (OAE). OAE testing checks whether the inner ear’s sensory cells are functioning by measuring a faint sound the ear naturally produces in response to stimulation. It is commonly used for newborn screening and does not require a behavioral response, but it does not provide the detailed, frequency specific threshold information that PTA does for older children and adults.

In many cases, your audiologist will recommend PTA alongside one or more of these tests for a complete picture, rather than PTA alone.

What Affects the Cost of a PTA Test in Pakistan

PTA test pricing varies based on a few practical factors, which is why it is worth understanding what you are actually paying for rather than comparing a single number across providers:

Single test versus a full diagnostic battery. A standalone PTA test is priced differently than a combined package that includes PTA alongside tympanometry or an audiologist consultation to interpret results and recommend next steps.

Air conduction only versus air and bone conduction. A complete PTA test measuring both air and bone conduction takes longer and provides more diagnostic information than an air conduction only screening, which can affect pricing.

Branch location. IHC operates across multiple cities in Pakistan, including Islamabad, Rawalpindi, Peshawar, Faisalabad, Multan, Karachi, Sargodha, and several others, and pricing can vary slightly by location.

Whether the test is a standalone visit or part of a hearing aid fitting process. PTA testing conducted as part of a hearing aid evaluation is sometimes bundled into the overall service rather than charged separately.

For the most accurate, current pricing at your nearest branch, it is best to contact IHC directly, since published estimates can go out of date while your actual clinic pricing reflects real time costs.

What to Expect at Your Appointment

Before the test itself, your audiologist will typically ask about your hearing history, any noise exposure, medications, or family history relevant to hearing loss. This context helps interpret your results more accurately once testing is complete. After the test, you will review your audiogram together, and if any follow up is needed, whether that is a medical referral, a repeat test, or moving toward hearing aid options, your audiologist will walk you through it directly. You can review the full range of tests offered at our hearing test page before booking.

If your doctor has referred your child for a BERA test, or if you have noticed something different about the way your baby or toddler responds to sound, you are likely searching for clear and trustworthy information right now. You want to understand what this test actually is, whether it is painful, what happens during the procedure, and how much it will cost you in Islamabad or anywhere else in Pakistan.

This guide answers every one of those questions. It is written by the team at Islamabad Hearing Center (IHC), Pakistan’s most advanced audiology network, which has been conducting professional hearing assessments for children and adults since 2009. By the time you finish reading, you will know exactly what to expect from the BERA test, why it matters, and where to get it done by qualified audiologists in Pakistan.

What Is the BERA Test?

BERA stands for Brainstem Evoked Response Audiometry. It is sometimes also called the ABR test, which stands for Auditory Brainstem Response. Both names refer to the same clinical procedure. The BERA test is an objective hearing assessment that measures how the auditory nerve and brainstem respond to sound. Unlike conventional hearing tests that require the patient to press a button or raise a hand when they hear a sound, the BERA test requires no voluntary response from the patient at all. This is precisely what makes it so valuable for infants, newborns, and young children who cannot participate in standard hearing tests.

The BERA test was first described scientifically by Jewett and Williston in 1971, and it has since become one of the most widely used and clinically validated hearing assessment tools in audiology worldwide. According to the American Speech-Language-Hearing Association (ASHA), the ABR/BERA test is considered the gold standard for evaluating hearing thresholds in populations that cannot be tested using conventional methods, including newborns, infants, and individuals with developmental or cognitive differences.

In Pakistan, the BERA test has become increasingly important as awareness of childhood hearing loss grows. Undetected hearing loss in a child’s early years can have a serious impact on speech development, language acquisition, cognitive growth, and social skills. The BERA test allows audiologists to identify hearing issues as early as the first few weeks of life, enabling intervention before these developmental delays can take hold.

Why Is the BERA Test Done?

Parents and doctors request the BERA test for several specific reasons, and understanding these helps you know whether your child needs it.

The most common reason is a failed newborn hearing screening. Many hospitals in Pakistan now conduct a basic Otoacoustic Emission (OAE) screening for newborns before discharge. If a baby does not pass this initial screen, a BERA test is the recommended follow-up assessment to confirm whether there is a true hearing problem or whether the initial result was a false alarm.

The second major reason is parental concern. If you have noticed that your baby does not startle at loud sounds, does not turn their head toward voices by 3 to 4 months of age, or is not babbling by 6 to 9 months, these are signs that should be taken seriously. A hearing test at this stage gives you the clinical information you need to act quickly.

The BERA test is also used for children with a family history of congenital hearing loss, children who were born prematurely, babies who experienced complications at birth such as lack of oxygen, children who have had severe jaundice or meningitis, and children who have been exposed to certain medications known to affect hearing. In all of these cases, waiting for a child to fail in school or in speech development before investigating hearing is too late.

Adults can also benefit from the BERA test. In adult patients, it is used to investigate suspected auditory nerve tumors, to evaluate unexplained dizziness or balance disorders, and to assess hearing in patients who are unable to complete standard audiometry.

How Does the BERA Test Work?

The BERA test measures the electrical activity generated by the auditory nerve and brainstem in response to sound stimuli. When a sound enters the ear, it travels through the outer and middle ear, reaches the cochlea in the inner ear, and is then converted into electrical impulses that travel along the auditory nerve to the brainstem and eventually to the brain. The BERA test records this electrical journey using electrodes placed on the surface of the scalp.

The result is a series of waveforms on a graph, each representing a specific point along the auditory pathway. Audiologists read these waveforms to determine whether sound is being processed normally at each stage, whether there is a delay or an abnormality in transmission, and what the patient’s hearing threshold is.

The entire process is completely passive. The patient does not need to do anything. The test works whether the patient is awake, asleep, or — in some cases — under light sedation. This makes it completely safe for newborns and infants.

What Happens During the BERA Test: Step by Step

Knowing exactly what will happen during your child’s appointment helps to reduce anxiety for parents and makes the session go more smoothly. Here is what you can expect at Islamabad Hearing Center when your child comes in for a BERA test.

Before the test: You will be asked to fill in a short clinical history form covering your child’s birth history, any illnesses, medications, or family history of hearing loss. The audiologist will review this information and speak with you about your concerns before beginning.

Electrode placement: Small, painless electrodes are placed on your child’s forehead, on the mastoid bone behind the ear, and on the earlobe or top of the head. These electrodes are connected to wires that lead to the BERA equipment. The electrodes do not deliver any electrical signal to your child — they only record the brain’s own electrical responses. No needles are involved.

Sound delivery: Your child is fitted with small earphones or insert phones. A series of click sounds or tone bursts are played through these earphones at various volumes and frequencies. The sounds are brief and quiet — they will not startle or distress your child.

Recording the response: The BERA equipment records the electrical responses generated by the auditory nerve and brainstem in response to each sound. The audiologist monitors the waveforms on the screen throughout the procedure.

Duration: The test typically takes between 45 minutes and 90 minutes depending on the child’s age and how cooperative they are. For sleeping infants, the test can often be completed in a single session without sedation. For older toddlers who may be more restless, the audiologist may suggest scheduling the appointment during a natural nap time or may recommend light sedation in consultation with a pediatrician.

Results: The audiologist will explain the results to you immediately after the test. You will receive a printed report of the waveforms with the audiologist’s clinical interpretation. If the results indicate any hearing loss, the audiologist will also guide you on the next steps, which may include further testing such as the ASSR Test or a referral for medical management.

Is the BERA Test Painful or Harmful?

This is the question parents ask most often, and the answer is clear: the BERA test is completely painless and non-invasive. No injections, no instruments inside the ear canal, and no electrical stimulation of any kind are involved. The electrodes simply sit on the skin surface and detect the brain’s natural electrical activity. The sounds played through the earphones are at safe listening levels, and the entire procedure carries no physical risk to your child.

The only challenge with young children is keeping them still enough for the electrodes to record clean signals. A sleeping or calm child produces the best quality results. This is why parents are often advised to keep their baby awake for a while before the appointment so the child is ready to sleep during the test, or to schedule the appointment during the child’s usual nap time.

BERA Test vs OAE Test: What Is the Difference?

Parents sometimes ask how the BERA test is different from the OAE test, which is the standard newborn hearing screen conducted in hospitals. Both tests are used for children and both are objective, but they measure different things at different levels of the auditory system.

The OAE test measures the response of the cochlear hair cells in the inner ear. It is a fast, simple test that gives a pass or refer result. It is excellent as a first-line screen but does not give information about the auditory nerve or brainstem. A child can pass an OAE test but still have auditory nerve dysfunction, a condition sometimes called auditory neuropathy.

The BERA test goes deeper into the system, measuring the function of the auditory nerve and the brainstem response. It provides detailed waveform data and can estimate hearing thresholds at different frequencies. For this reason, the BERA test is used as the confirmatory test when an OAE screen gives a refer result, and it is the test of choice for diagnosing the specific type and degree of hearing loss.

Our new born screening program at IHC includes both OAE and BERA assessments, giving families a comprehensive picture of their child’s hearing health from the very first days of life.

What Can the BERA Test Detect?

The BERA test provides clinically valuable information across several categories of hearing and neurological assessment.

It can confirm whether a hearing loss is present at all, which is particularly important in cases where standard behavioural testing is not yet possible due to a child’s age. It can identify the type of hearing loss — whether conductive (involving the outer or middle ear), sensorineural (involving the inner ear or auditory nerve), or neural (involving the auditory nerve specifically, as in auditory neuropathy spectrum disorder). It can estimate the degree of hearing loss across different pitches or frequencies. It can identify retro cochlear pathology, which refers to problems beyond the cochlea, such as auditory nerve tumors or brainstem lesions, making it relevant for adult patients too. And it can assess the integrity of the brainstem auditory pathway, which has clinical applications in monitoring patients in intensive care, during neurosurgery, or after head injuries.

For parents, the most important practical output is simply knowing whether their child’s hearing is within normal limits or whether there is a problem that requires intervention. Early identification of hearing loss allows families to access hearing aids, auditory rehabilitation, and speech therapy at the earliest possible age, which research consistently shows leads to dramatically better outcomes for speech, language, and educational development.

According to the World Health Organization, over 430 million people globally have disabling hearing loss, and early intervention remains the most effective strategy for minimizing its long-term impact on quality of life. In Pakistan, where awareness of hearing loss screening in newborns is still growing, the BERA test plays a critical role in catching problems that would otherwise go undetected for years.

BERA Test Cost in Pakistan: What to Expect in Islamabad

One of the most searched questions related to the BERA test in Pakistan is about cost. Parents want to know what they will pay before they commit to an appointment, and this is completely reasonable. Transparency in healthcare pricing builds trust and helps families plan.

The cost of the BERA test in Pakistan varies depending on the city, the facility, and the technology being used. At a well-equipped audiology center with properly calibrated equipment and qualified audiologists, the price in Islamabad typically falls in a range that reflects the clinical expertise and technology involved. Basic BERA tests at less equipped facilities may be offered at lower prices, but the quality of the waveform data and the accuracy of interpretation depends entirely on the equipment and the experience of the audiologist reading the results.

At Islamabad Hearing Center, the BERA test is conducted using advanced diagnostic equipment by certified audiologists trained in multiple countries. We believe that parents seeking answers about their child’s hearing deserve the highest standard of clinical testing, not just the cheapest available option. For the latest pricing and to book an appointment, we encourage you to call our team directly at 051 8899990 or WhatsApp us at +92 336 5784920. You can also visit our contact page to reach the branch nearest to you.

We serve patients across Islamabad, Rawalpindi, Peshawar, Faisalabad, Karachi, Multan, Sargodha, Muzaffarabad, Rawalakot, and Bagh City. If you are outside Islamabad, our branch network means you can access the same standard of BERA testing closer to home.

What Happens After the BERA Test?

The result of the BERA test shapes the next steps in your child’s care pathway. If the results are normal, it means the auditory nerve and brainstem are responding to sound within expected parameters. Normal BERA results give parents significant reassurance and rule out sensorineural hearing loss as the cause of any concerns.

If the results show a mild, moderate, or severe hearing loss, the audiologist will explain exactly what this means in practical terms and what options are available. For most forms of sensorineural hearing loss in children, digital hearing aids are the primary intervention. At IHC, we carry hearing aids from the world’s leading brands including Phonak, Signia, Widex, Oticon, and Starkey, and we provide fitting, programming, and ongoing support through our hearing aid services. For cases of profound hearing loss where hearing aids do not provide sufficient benefit, a cochlear implant evaluation may be recommended.

If the BERA results suggest auditory neuropathy spectrum disorder, a more specific pattern of intervention is required, and the audiologist will guide you through this in detail. In some cases, additional tests such as the ASSR Test or Tympanometry are conducted alongside the BERA to build a complete picture of the child’s hearing profile before deciding on a management plan.

The key message is this: whatever the result, a BERA test gives you information you can act on. Not knowing is always worse than knowing, because only with a clear diagnosis can you begin the journey toward better hearing for your child.

When Should You Book a BERA Test?

Do not wait for a formal referral if you have concerns about your child’s hearing. The earlier a hearing problem is identified and addressed, the better the outcome for the child’s speech, language, and cognitive development. The critical window for language acquisition is the first three years of life, and hearing loss that goes undetected during this period can cause delays that are much harder to reverse later.

If your newborn did not pass the hospital hearing screen, book a BERA test within the first few weeks. If your infant is three to four months old and not responding to voices or loud sounds, book a test now. If your toddler is not babbling, is not using words by 12 to 15 months, or seems to hear only when they want to, do not put off the assessment. If a family member has congenital hearing loss or your child had a difficult birth, early screening is strongly advised regardless of whether you have noticed any concerns.

Frequently Asked Questions About the BERA Test in Pakistan

At what age can the BERA test be done?

The BERA test can be performed from the first days of life onwards. There is no minimum age. For newborns and very young infants, the test is typically done while the baby is in a natural sleep. For children above six months who may not sleep naturally during the test, the audiologist may coordinate with a paediatrician for light sedation if needed.

Does the BERA test require sedation?

Not always. Many infants and young children can be tested while naturally asleep without any sedation. For older toddlers or children who are difficult to settle, light sedation may be recommended by the managing paediatrician to ensure a quality recording. The decision is made case by case based on the child’s age and behaviour.

Can the BERA test give a false result?

The BERA test is highly reliable when conducted with properly calibrated equipment by an experienced audiologist. A false positive result is rare. In some cases, a second test may be recommended to confirm findings, particularly for borderline results or when the recording quality was affected by movement artifacts.

Is the BERA test available outside Islamabad in Pakistan?

Yes. Islamabad Hearing Center offers BERA testing at branches in Rawalpindi, Peshawar, Faisalabad, Karachi, Multan, Sargodha, Muzaffarabad, Rawalakot, and Bagh City. Contact us to confirm availability at your nearest branch.

What should I bring to the BERA test appointment?

Bring any previous hearing test reports if available, your child’s vaccination card for age confirmation, and any referral letter from your doctor. If your child takes regular medication, inform the audiologist before the appointment. For infants, bring feeding supplies to help settle the child to sleep during the test.

Your child’s hearing matters. The right test, at the right time, from the right team, can change everything.

The first two days of a baby’s life are full of firsts first breath, first cry, first feeding, first sleep in a new world. For parents, these hours are consumed by wonder, exhaustion, and a thousand small decisions.

But hidden inside those 48 hours is a window of opportunity that most Pakistani families are not yet fully aware of a window in which a short, simple, painless set of tests can detect conditions that, left unidentified, could rob a child of normal hearing, normal development, or even a healthy life.

This is newborn screening. And it is one of the most important and underutilised tools in preventive medicine in Pakistan today.

In countries where universal newborn screening programmes are well established the United States, United Kingdom, Australia the conditions it detects are caught routinely, treated early, and managed so effectively that most affected children grow up indistinguishable from their peers. In Pakistan, awareness and availability of these tests is growing, but significant gaps remain.

This guide is for every parent who wants to understand what newborn screening tests exist, what conditions they detect, how they work, and most importantly how to make sure their baby receives them.

What Is Newborn Screening? A Clear Definition

Newborn screening is the collective term for a group of medical tests performed on a baby shortly after birth typically within 24 to 72 hours to identify conditions that are present from birth but do not yet show outward symptoms.

The defining characteristic of newborn screening is its timing. These conditions are not detectable from a physical examination alone, and many produce no obvious signs in the early weeks of life. By the time symptoms become apparent without screening delayed development, abnormal growth, hearing difficulties, metabolic crises significant and often irreversible damage may already have occurred.

Screening before symptoms appear is what makes these tests so powerful. Early detection opens a treatment window that simply does not exist once the condition has had weeks or months to affect the developing brain, nervous system, or body.

Newborn screening is not a single test it is a programme comprising two to four distinct assessments depending on the hospital and the region. In Pakistan’s more progressive hospitals, this currently includes a blood spot test (heel prick), a newborn hearing screen, and a pulse oximetry check for congenital heart disease. At Islamabad Hearing Center, newborn hearing screening is a core part of what we offer through our newborn hearing screening service.

Why Is Newborn Screening Done Right After Birth?

Timing is everything in newborn screening for two interconnected reasons.

First, many conditions are present and active from the moment of birth but have not yet caused damage. Congenital hypothyroidism, for example the most commonly detected condition in newborn screening programmes globally begins affecting a baby’s thyroid function from the earliest days of life. Left untreated, it causes severe intellectual disability and growth failure. Detected within the first two weeks and treated with a simple daily tablet, outcomes are virtually normal. The treatment is inexpensive. The damage without it is profound. The difference between these two outcomes is entirely determined by the timing of detection.

Second, the brain and auditory system develop at a pace in the first year of life that is never replicated again. For children with hearing loss, the window of maximum neuroplasticity the period in which the auditory brain most readily forms the neural connections required for language runs from birth to approximately three years of age. Every month of untreated hearing loss in this window narrows the ultimate language outcomes. Detection at birth and treatment within the first six months produces dramatically better speech and language development than detection at two or three years even when the treatment is identical.

This is why the International Joint Committee on Infant Hearing recommends a standard known as 1-3-6: screen by one month, diagnose by three months, and enrol in early intervention by six months of age. In Pakistan, achieving this timeline begins with a newborn hearing test in the hospital, ideally before the baby is discharged.

10 Conditions Detected Through Newborn Screening in Pakistan

Not every hospital in Pakistan screens for all of these conditions the panel varies by institution and by region. However, these are the conditions for which newborn screening is clinically recommended and increasingly available:

1. Congenital Hypothyroidism

The most commonly detected and most treatable condition in newborn screening worldwide. The thyroid gland fails to produce sufficient hormone from birth. Without treatment: severe intellectual disability, stunted growth, and permanent developmental delay. With daily thyroid hormone tablets started within the first two weeks: near-normal development in the vast majority of cases.

2. G6PD Deficiency

Glucose-6-phosphate dehydrogenase deficiency is among the most prevalent genetic conditions in South Asian populations, including Pakistan. It causes red blood cells to break down when exposed to certain medications, foods, or infections. Identified early, it is entirely manageable through dietary guidance and medication awareness. Unidentified, it can cause severe haemolytic crises including in newborns exposed to common medications that are preventable with simple precaution.

3. Phenylketonuria (PKU)

A metabolic disorder in which the body cannot process phenylalanine, an amino acid found in most protein-containing foods. Without screening and dietary management from the earliest weeks of life, phenylalanine accumulates and causes severe, irreversible brain damage. With early detection and a specialised low-phenylalanine diet, children with PKU develop normally and lead full lives.

4. Congenital Adrenal Hyperplasia (CAH)

A group of genetic disorders affecting the adrenal glands’ ability to produce essential hormones. In its most severe form, it causes life-threatening salt-wasting crises in the first weeks of life crises that are entirely preventable with hormone replacement therapy started immediately after detection.

5. Hearing Loss

Hearing loss is one of the most common birth conditions worldwide, affecting approximately 1-3 per 1,000 newborns in developed countries and likely higher in Pakistan due to elevated rates of consanguineous marriage and limited antenatal care access in some regions. Unlike the other conditions in this list, newborn hearing screening is not performed through a blood test it uses a quick, painless Otoacoustic Emissions (OAE) test or an ABR test that measures the inner ear’s response to sound.

Detection at birth versus detection at two or three years is not a small difference in outcome it is the difference between a child who develops normal language and one who requires years of intensive speech therapy to achieve partial communication. Early detection enables early hearing aid fitting and, where required, referral for cochlear implant evaluation.

For children who do not pass their initial newborn hearing screen, a BERA test provides definitive diagnostic information about the type and degree of hearing loss allowing the right intervention to begin as early as possible.

6. Sickle Cell Disease

Sickle cell disease causes red blood cells to form an abnormal crescent shape, leading to blockages in blood vessels, severe pain episodes, organ damage, and increased infection risk. Detected through newborn screening, children can receive prophylactic penicillin from the first months of life dramatically reducing life-threatening infections and their families can be counselled on crisis prevention.

7. Beta-Thalassaemia

Beta-thalassaemia is extremely prevalent in Pakistan, which has one of the highest rates of thalassaemia carriers globally. While the severe form (thalassaemia major) cannot be cured by early detection alone, identification at birth enables earlier transfusion therapy, iron chelation management, and most importantly genetic counselling for the family regarding future pregnancies.

8. Congenital Heart Disease (Pulse Oximetry Screen)

A simple pulse oximetry reading a small clip placed on the baby’s hand or foot that measures blood oxygen levels can detect critical congenital heart defects that may not be apparent from a physical examination. Detected early, surgical or catheter intervention can be life-saving. Missed in the newborn period, critical heart defects can cause sudden deterioration at home in the first weeks of life.

9. Cystic Fibrosis

A genetic condition affecting the lungs and digestive system. Early detection through newborn screening enables nutritional support, physiotherapy, and preventive treatment to begin before any lung damage has occurred significantly improving life expectancy and quality of life outcomes.

10. Biotinidase Deficiency and Other Metabolic Conditions

A group of rare but treatable metabolic disorders detectable through the heel prick blood spot. Without treatment, they cause seizures, developmental delay, and vision loss. With a daily biotin supplement one of the simplest and least expensive treatments in all of medicine affected children develop entirely normally.

How Is the Newborn Screening Test Performed?

The process is straightforward, quick, and causes minimal discomfort.

The heel prick blood spot test: A small amount of blood is collected from the baby’s heel a brief squeeze that causes momentary discomfort, after which babies typically settle within seconds. The blood is applied to special filter paper cards and sent to a laboratory for analysis. Results are typically available within one to two weeks.

The newborn hearing screen: A small, soft probe is placed briefly in the baby’s ear canal. The Otoacoustic Emissions test sends a quiet sound into the ear and measures the echo produced by the healthy inner ear in response. The entire test takes around five minutes per ear and is completely painless most babies sleep through it. If the initial screen does not give a clear result (which can happen due to fluid in the ear canal after birth), a repeat test or a more detailed ABR test or BERA test is arranged.

The pulse oximetry check: A small sensor is clipped to the baby’s hand or foot for a few minutes. It reads blood oxygen saturation and heart rate and requires no procedure of any kind.

The entire newborn screening programme, when performed in a well-equipped hospital, adds perhaps 20 to 30 minutes to the standard post-delivery care process and causes no harm to the baby.

Is Newborn Screening Mandatory in Pakistan?

Not universally and this is one of the most significant gaps in Pakistan’s child health system.

In most developed countries, newborn screening is a legal requirement a right enshrined in child health policy. In Pakistan, no federal law currently mandates a comprehensive newborn screening programme across all hospitals and provinces. Some private hospitals in Islamabad, Lahore, and Karachi have established their own newborn screening protocols. Government hospitals vary significantly in what is offered, with newborn hearing screening in particular being inconsistent across public sector maternity facilities.

The Pakistan Paediatric Association and audiology professional bodies have advocated strongly for a national newborn screening programme. Progress is being made but until universal screening becomes policy, the responsibility falls on parents and their healthcare providers to ensure these tests are requested and performed.

According to the World Health Organization’s report on early childhood hearing loss, countries that establish universal newborn hearing screening programmes see a dramatic reduction in the age of hearing loss diagnosis from an average of 2–3 years without screening to under 3 months with it. The cascade of developmental benefits from this single shift in detection timing is substantial.

If you are expecting a baby or have recently delivered, ask your hospital or obstetrician directly: which newborn screening tests are offered, when they are performed, and what the follow-up pathway is if a result is abnormal. If your hospital does not offer a newborn hearing screen, contact Islamabad Hearing Center our newborn hearing screening service is available for babies referred from hospitals that do not yet have this capability in-house.

What Happens If a Problem Is Found?

An abnormal screening result is not a diagnosis it is a signal for further investigation. It is important to understand this distinction clearly, because an abnormal initial screen can be caused by factors unrelated to the condition being screened for.

For blood spot results: If the laboratory flags an abnormal result, your paediatrician will arrange confirmatory testing immediately. Many initial flags are resolved by the confirmatory tests. If a condition is confirmed, specialist management begins without delay.

For hearing screens: A baby who does not pass the initial OAE hearing screen should have the test repeated, ideally within two to four weeks. Fluid in the ear canal common in the days immediately after birth is a frequent cause of initial screen failures that resolve spontaneously. If the repeat screen also does not pass, a diagnostic BERA test or ASSR test is performed to determine whether hearing loss is present and, if so, its type and degree. From this point, the pathway to hearing aids or cochlear implant evaluation can begin rapidly enough to meet the 1-3-6 guideline timelines.

Our blog on the benefits of early detection through hearing tests explains in detail how early intervention changes developmental outcomes for children with hearing loss identified in the newborn period.

The Benefits of Early Detection – Why Every Week Counts

The medical case for newborn screening is not subtle or contested. The evidence accumulated over six decades of screening programmes worldwide is consistent and clear:

Every condition detected through newborn screening that receives early treatment produces dramatically better outcomes than the same condition detected late. The gap in outcomes is not marginal in conditions like congenital hypothyroidism, PKU, and congenital hearing loss, the difference between early and late detection is the difference between a child who develops normally and one who does not.

For hearing loss specifically, the research is unambiguous. Children identified at birth and fitted with appropriate amplification before six months of age consistently achieve language development scores within the normal range for hearing children. Children identified at age two or three even with identical treatment require years of intensive speech therapy and often never fully close the language gap.

For Pakistani families, the implications are direct. The 10 early signs of hearing loss you should never ignore are visible only after a delay that newborn screening eliminates entirely. Waiting for signs is waiting for a problem that has already had months or years to develop.

How to Ask Your Hospital About Newborn Screening in Pakistan

Knowing what to ask is the first practical step:

Before delivery: Ask your obstetrician or midwife which newborn screening tests are performed at your chosen hospital. Ask specifically about the blood spot programme, the newborn hearing screen (OAE), and pulse oximetry. If any are not offered, ask how to arrange them independently.

At delivery: Remind nursing staff that you want all available newborn screening tests performed before discharge. Do not assume they will happen automatically confirm.

If your baby does not pass the hearing screen: Ask for the repeat test to be scheduled before leaving the hospital, or ask for a referral to a specialist audiology clinic for follow-up. Do not wait. Contact Islamabad Hearing Center if you need to arrange a BERA test or a diagnostic hearing evaluation outside your delivering hospital.

Document everything: Keep the screening results in your child’s health records. If you change paediatricians or move to a different city, these records travel with your child and prevent gaps in follow-up care.

Frequently Asked Questions

What is newborn screening and what does it test for in Pakistan?

Newborn screening is a group of safe, painless tests done within 72 hours of birth to detect serious but treatable conditions before symptoms appear. In Pakistan, commonly available tests include a blood spot (heel prick) for metabolic and genetic conditions like congenital hypothyroidism, G6PD deficiency, and PKU; a hearing screen using Otoacoustic Emissions; and a pulse oximetry check for congenital heart disease.

Is the newborn screening test painful for babies?

The heel prick causes a brief moment of discomfort equivalent to a light squeeze from which babies settle within seconds. The hearing screen and pulse oximetry check are completely painless and non-invasive. Most babies sleep through the hearing test. There is no lasting discomfort from any component of the standard newborn screening programme.

Is newborn screening mandatory in Pakistan?

No federal law currently mandates comprehensive newborn screening across all Pakistani provinces and hospitals. However, it is strongly recommended by the Pakistan Paediatric Association and international health bodies. Private hospitals in major cities increasingly offer it as standard. Parents should proactively request all available screening tests from their delivering hospital.

What happens if my baby does not pass the newborn hearing screen?

A screen failure does not confirm hearing loss it means further testing is needed. Fluid in the ear canal, which is common immediately after birth, frequently causes a screen failure that resolves with a repeat test two to four weeks later. If the repeat screen also fails, a diagnostic BERA test or ABR test is arranged to determine whether hearing loss is present and what form it takes.

Which conditions can newborn screening detect that parents most commonly miss?

Congenital hypothyroidism and G6PD deficiency are the most commonly detected conditions that parents would have no way of identifying without screening they cause no visible symptoms in the newborn period. Hearing loss is the most common birth condition overall, and is easily missed because babies with hearing loss behave normally in most respects during the early weeks of life.

Where can I get a newborn hearing screening in Islamabad?

Islamabad Hearing Center provides newborn hearing screening for babies referred from hospitals that do not perform the test in-house, as well as for families who wish to have their newborn’s hearing assessed independently. Contact us through our newborn screening page or contact us directly to arrange an appointment.

Prevention Is the Most Powerful Medicine Available

The conditions that newborn screening detects share a common characteristic: they are present from birth, they are largely invisible in the early weeks, and they are far more treatable when caught early than when caught late.

For Pakistani families, the message is simple. Ask for these tests. Insist on the hearing screen before your baby is discharged. If your hospital does not offer it, arrange it independently. The tests take minutes. The conditions they find, if left undetected, take years sometimes decades to manage. The investment of those minutes is among the most consequential health decisions a parent can make.

If your baby has not had a newborn hearing screen, or if you have concerns about your young child’s hearing development at any age, Islamabad Hearing Center is here to help. Our certified audiologists conduct newborn hearing screening, BERA diagnostic tests, and full paediatric audiology assessments all in a child-friendly, supportive environment.
