My daughter was born three weeks early. When she was two months old, she did not react to loud sounds. She would not turn her head when I clapped near her ear. Her pediatrician suggested an auditory brainstem response test. I had never heard of it. The doctor explained that ABR test is the short form. I was terrified. But after going through the ABR test with my baby, I want to explain what it is so other parents do not panic like I did.

What Is an Auditory Brainstem Response Test

An auditory brainstem response test measures how the hearing nerve and brain react to sound. The ABR test does not require the patient to do anything. You do not have to press a button or raise your hand. This makes the auditory brainstem response test perfect for newborn babies. In an ABR test, small stickers called electrodes are placed on the head and behind the ears. Soft earphones are put in the ears. Clicking sounds are played, and the electrodes record how the brain responds. The whole ABR test takes about thirty to forty minutes.

Why My Baby Needed an Auditory Brainstem Response Test

My baby did not react to sounds. The doctor wanted to know if her hearing nerve was working. The auditory brainstem response test showed that my baby had some response to loud sounds but not to soft ones. That told us there was hearing loss but not exactly how much. The ABR test gave us a starting point. Without the ABR test, we would have had no idea what was wrong.

How Auditory Brainstem Response Test Is Different from Other Hearing Tests

An auditory brainstem response test is more detailed than a simple hearing screening. While a basic screening tells whether the baby reacts to sound, the ABR test actually measures the brain's electrical response. The ABR test can tell if the hearing nerve is damaged. It can also tell if the problem is in the brainstem. The auditory brainstem response test is painless and safe. My baby slept through the entire test.

How to Prepare a Child for an Auditory Brainstem Response Test

The ABR test requires the child to be completely still or asleep. My baby was given a mild sedative syrup thirty minutes before the test. She slept through the entire auditory brainstem response test without any discomfort. The electrodes do not hurt. They feel like small sticky bandages being removed. Some hospitals perform the ABR test during natural sleep if the baby is very young and tired. But for older children, sedation is usually needed. Do not be afraid of sedation. The dose is very small and wears off within two hours.

What the ABR Test Results Meant for Us

The auditory brainstem response test gave us a clear picture. We started early intervention when my baby was only three months old. She got hearing aids before her first birthday. Now she is two years old and speaks almost as well as other children her age. If we had not done the ABR test early, she would have missed critical years for language development. I tell every new parent I meet that newborn hearing screening should include an auditory brainstem response test if possible.

Final Words for Worried Parents

I know the name auditory brainstem response test sounds scary. It sounds like a big machine and a complicated procedure. But the reality is very simple. Your child sleeps through the ABR test. You sit in the same room. A kind technician does all the work. The results come in a clear graph that even a non medical person can understand. If the ABR test shows a problem, you get help early. If the test is normal, you get peace of mind. There is no downside. Please do not delay.
