Auditory Brainstem Response (ABR) is a computerized neurological test of auditory brainstem function that may be ordered for one or more of the following symptoms:
- Vertigo or Dizziness
- Unilateral or Asymmetrical hearing loss
- Ringing or Buzzing in the Ears (Tinnitus)
- Fullness in the Ears
The ABR is a simple test that evaluates the auditory nerve for any rare growths or abnormalities. This test will reveal whether or not the auditory nerve and lower brainstem are functioning properly.
During testing, you will be in a reclined position with your eyes closed. Sticker electrodes will be placed on your head and behind your ears. You will hear multiple series of a loud clicking sound though earphones in your ear canals. There will not be any discomfort during the test. Testing usually takes 45 minutes to complete. The more relaxed you are, the more quickly the test will run (some people even fall asleep). Please do not wear any makeup on your forehead on the day of the test, as the sticker electrodes get better contact with clean skin.
All medications can be taken prior to testing. You can drive yourself to and from the appointment. Please avoid alcohol the evening before the test and avoid excessive caffeine the morning of the test. Caffeine may make you unable to relax. You may resume normal activities after the testing is complete.
In the event of thunder and/or lightning in the area of the Duluth office, we will be unable to perform your ABR until the weather has cleared. Please call our office if you have any questions regarding the weather on the morning of your test.
Our office requires 48 hour notice for all cancellations or rescheduling.
Failure to provide adequate notice will result in a $50 fee per test.
