Ear Center: Pediatric Auditory Brainstem Response Testing (ABR)
About The ABR Test
Please confirm your child's appointment time with our receptionists by calling (336) 273-9932.
Your child's physician has ordered a special type of hearing/auditory nerve test called an "Auditory Brainstem Response Test" or ABR. The purpose of the test is to aid in the evaluation of your child's hearing. During the test procedure, your child will rest in a quiet environment while listening to "click" sounds through insert earphones placed in their ear canals. Four (4) snap electrodes will be taped to your child's mid and lower forehead as well as behind their ear (mastoid region) or lobe of each ear. NO NEEDLES ARE USED. THERE IS NO DISCOMFORT FROM THE ELECTRODES. The audiologist will be measuring small electrical impulses generated by the brain when the hearing nerves are stimulated by sound. With a computer, the audiologist will evaluate your child's "brain wave activity" in response to sound.
Please make plans to arrive on time, and call us if you think that you will be delayed . If you arrive more than 10 minutes late, we will need to reschedule the test as there will not be enough time for us to complete the evaluation.
The ABR Test:
During the ABR test, it is very important for your child to remain as still and quiet as possible. You will be asked to assist your child. Excessive movement creates electrical artifact from muscle activity that interferes with the ABR test. It is important that your child arrive at the office tired and/or sleepy. We recommend that you keep your child up late the night before the test and awaken him/her early in the morning on the day of the test. Please bring along any object(s) that will help your child feel more comfortable (a favorite blanket, bottle, stuffed animal, etc.) and assist him/her in falling asleep There is no discomfort associated with the ABR test. Your child should be able to remain asleep during the entire test. If your child awakens during the test or if there is too much movement artifact, he/she may need to be retested in order to obtain accurate results.
Results of the ABR will not be available on the day of testing. The data collected must be analyzed and then reviewed by one of our physicians. If you do not have a scheduled follow-up appointment with your doctor, an audiologist will contact you to discuss the results.
We look forward to seeing you and your child at your appointment.
If you have any questions concerning your child's appointment, please call us at (336) 273-9932 and ask for the Audiology Department.
