The auditory brainstem response (ABR) test, also called an auditory evoked potential (AEP), gives information about the inner ear and brain pathways for hearing. Electrodes are placed on the head that record brain wave activity in response to sound. The person being tested needs to rest quietly or be asleep during the test.
It can also be used as a screening test for newborns.
Who is auditory brainstem response (ABR) test for?
ABR is useful for children or adults who have difficulties with other hearing tests in addition to individuals with signs of hearing loss in the brain or brain pathway. It can also be used as a screening test for newborns; however, only one loudness level will be checked, and the infant will either pass or fail the screen.
