Bringing a baby into the world is a joyful moment, but when your newborn needs NICU intensive care, it can feel overwhelming. If your little one has been admitted to a Neonatal Intensive Care Unit, you will notice a lot of gentle activity around them, including several small tests. Knowing what these tests are and why they are done can help you feel calmer and more involved in your baby’s care.
At Anandi Hospital, our neonatal team sits within our maternity hospital, so we look after newborns and their parents together every day. We believe informed parents are confident parents. Here is a simple, honest look at the common tests and newborn screening tests your baby may have during their NICU stay.
Why Newborns Are Tested in the NICU
Some babies need extra support in their first days, often because they arrived early, have a low birth weight, or developed a health concern soon after birth. Tests give the neonatal team a clear picture of how your baby is doing, so any problem can be spotted and treated early, sometimes before symptoms even appear. In our day-to-day care of newborns, we have found that these early checks are what allow small concerns to be managed before they grow into bigger ones. Most of these tests are quick, gentle, and cause little or no discomfort to your baby.

Newborn Screening Tests
Newborn screening tests check for rare but serious conditions that are not visible at birth. In our experience caring for newborns in Aurangabad, early screening makes a real difference, because many of these conditions respond very well to treatment when caught in the first few days.
The most common newborn screening is the heel prick blood test. A few drops of blood are taken from your baby’s heel onto a filter paper and checked for metabolic, genetic, and hormonal disorders such as congenital hypothyroidism and G6PD deficiency. It is a small prick that offers reassurance about several conditions at once.
Screening usually also includes a hearing test and a heart screening. The hearing test uses a soft earphone and tiny sensors to check how your baby responds to sound, which helps protect speech and language development later on. The heart screening, done using a pulse oximeter on the hand or foot, measures oxygen levels to detect certain congenital heart concerns.
If your baby was born very early or received a blood transfusion, some screening tests may be repeated for accuracy. If you would like to understand your options, our neonatal team is always happy to explain each step before it is done.
Common Blood Tests
Blood tests are the most frequent checks in the NICU. They tell the team a great deal in a very short time. Common blood tests look at:
- Blood sugar levels, since small and premature babies can struggle to keep their sugars stable
- Bilirubin levels, to check for newborn jaundice, which is common and usually easy to treat
- Signs of infection, so any concern can be treated promptly
- Haemoglobin and blood counts, to check for anaemia
To reduce discomfort, our team often collects several samples together and uses the smallest amount of blood possible, an approach we follow with every baby in our unit.

Imaging and Monitoring Tests
Alongside blood tests, some babies need imaging to give doctors a closer look.
An ultrasound uses gentle sound waves, not radiation, to create pictures of your baby’s organs. A cranial (head) ultrasound is often used for premature babies to check the brain. An echocardiogram, which is an ultrasound of the heart, helps the team study how the heart is working and rule out heart defects. In some cases, an X-ray or other scan may be advised.
Your baby is also connected to soft monitors that continuously track heart rate, breathing, and oxygen levels. This means any change is noticed straight away, day or night.
Talking to Your Baby's Care Team
You have every right to understand what is happening with your child. Before any test, feel free to ask what it checks, why it is needed, and what the results mean. Our neonatal team always takes the time to explain things in plain language and keep you involved in decisions, because we have seen how much calmer parents feel once they understand the reason behind each check. Being present and asking questions is not a bother; it is an important part of your baby’s care.

Frequently Asked Questions (FAQs)
1. What tests are commonly done for babies in the NICU?
Common NICU tests include blood sugar and bilirubin tests, blood counts, infection screening, newborn screening tests, hearing tests, heart screening, and imaging such as ultrasound or X-rays. The tests recommended depend on your baby’s gestational age, birth weight, symptoms and overall health.
2. What is a newborn screening test?
A newborn screening test checks for certain rare but serious health conditions that may not be visible at birth. Screening may include a heel prick blood test, hearing test and heart screening using a pulse oximeter. Some babies may need repeat screening depending on their medical circumstances.
3. Why do premature babies need more tests in the NICU?
Premature and low-birth-weight babies may have a higher risk of problems with blood sugar, breathing, infection, jaundice and other conditions. Regular tests and monitoring help the neonatal team identify changes early and provide appropriate treatment when needed.
4. Are NICU tests painful for newborns?
Most NICU tests are designed to be quick and as gentle as possible. Some tests, such as a heel prick or blood sample, involve a brief prick, while monitoring, hearing screening and ultrasound are generally non-invasive. NICU teams also use techniques to minimise discomfort during necessary procedures.
5. What imaging tests may be performed on a baby in the NICU?
Depending on your baby’s condition, doctors may recommend a cranial ultrasound, echocardiogram, X-ray or another scan. A cranial ultrasound can assess the baby’s brain, while an echocardiogram uses ultrasound to examine the heart. The neonatal team will recommend imaging based on your baby’s individual needs.
