Your baby may have tests in the NICU to find out about health conditions and treatments she needs to grow and be healthy.
Some tests, like blood tests, are really common, and lots of babies get them. Others are just for babies with certain health conditions.
Before providers can do certain tests on your baby, you have to give permission. This is called informed consent.
Talk to your baby’s provider about tests your baby needs. Make sure you understand the test and why your baby needs it before you give permission.
Why do babies have tests in the NICU?
Your baby’s health care providers in the newborn intensive care unit (also called NICU) staff give your baby medical tests to find out about your baby’s health conditions. Test results help providers know what treatment your baby needs. For example, providers may do a blood test to check your baby for anemia. Anemia is when your baby doesn’t have enough healthy red blood cells to carry oxygen to the rest of her body. Or providers may take an X-ray to check your baby for a lung infection. Your baby’s provider tells you what tests your baby needs and tells you the test results.
Before providers can do certain tests, they need your consent. This means they’ll ask you to read and sign a consent form. When you sign the form, you give them permission to do the test. Sign the form only when you understand what the test is and why your baby needs it. Ask your baby’s providers any questions you have about the test before you sign the form.
What tests may your baby have in the NICU?
blood test — Tests your baby’s blood for certain health conditions. Blood tests are the most common tests done in the NICU. Test results give providers important information about your baby’s health. They also help providers find possible problems before they become serious.
CAT scan or CT scan — Also called computed tomography scan. A test that takes pictures of the inside of the body. It’s like an X-ray, but it gives a clearer, three dimensional (also called 3D) view. Your baby goes to the radiology department for the test. She may need medicine to help keep her still during the test.
echocardiogram — A special kind of ultrasound that takes pictures of the heart. Ultrasound uses sound waves and a computer screen to make the pictures. Providers use this test to help find heart problems, including heart defects. A heart defect is a problem with the heart that’s present at birth.
EKG or ECG— Also called electrocardiogram. A test that records the heart’s electrical activity. An EKG can show how fast your baby’s heart is beating and if the rhythm of the heartbeat is regular.
hearing test — Also called brainstem auditory evoked response test or BAER. This test checks your baby’s hearing. A provider places a tiny earphone in your baby’s ear and puts small sensors on his head. The provider plays sounds through the earphones, and the sensors send information to a machine that measures your baby’s response to the sounds. All babies get this test as part of newborn screening.
MRI— Also called magnetic resonance imaging. This test uses strong magnets and radio waves to take detailed pictures of the inside of your baby’s body. An MRI gives a more detailed view than a CT scan, X-ray or ultrasound. Your baby may need medicine to help keep her still during the test.
newborn screening test — Checks for serious but rare and mostly treatable conditions at birth. It includes blood, hearing and heart screening.
ROP exam— Also called retinopathy of prematurity exam or eye exam. Providers use this test most often for babies born before 30 weeks of pregnancy or babies who weigh less than 3 1/3 pounds. An eye doctor (also called an ophthalmologist) checks to see if the blood vessels in your baby’s eyes are developing the right way. If the doctor sees signs of problems, he checks your baby’s eyes over time to see if the condition gets better or if it needs treatment.
ultrasound — A test that uses sound waves to make pictures of the inside of the body. A provider puts a special jelly on your baby’s skin over the area of the body she wants to check. Then she rolls a small device shaped like a microphone over the area. Providers often use ultrasound to check for bleeding in your baby’s brain.
urine test — Tests a baby’s urine for certain health conditions. Urine test results can tell providers a lot about your baby’s overall condition. For example, test results can tell provider if your baby’s getting enough fluid, how your baby’s kidneys are working and if your baby has an infection. Your baby’s provider inserts a thin tube called a urinary catheter in the opening where urine passes out of your baby’s body to collect the urine.
weight — Weighing your baby at birth and as he grows and develops. Providers weigh your baby soon after birth and at least once a day in the NICU. It’s a good sign when babies start to gain weight at a steady rate.
x-ray — A test that uses small amounts of radiation to take pictures of the inside of your baby’s body. X-rays show pictures of your baby’s lungs and other organs. If your baby has breathing problems, she may need several lung X-rays each day. X-rays expose your baby to radiation, but the amount is so low that it doesn’t affect her health now or in the future. Radiation is strong energy that can be harmful to your baby’s health if she’s exposed to too much.
