Candice's ABR Test

On Monday, Candice is having a sedated hearing test. This will determine if Candice has any hearing loss. She has failed all her previous hearing tests and due to her age and still not having a clear answers, she will undergo this test and we will be able to determine if there is a hearing loss. She was suppose to have this test done earlier in the year, but due to sickness and conflicts that occured with the hospital, we are getting it in right before the end of the year.

It is called an Auditory brainstem response (ABR) test.

"An infant is sleeping or sedated for the ABR. An infant may be sleeping naturally or may have to be sedated for this test. Additionally, older, cooperative kids may be tested in a silent environment while they're visually occupied. Tiny earphones are placed in the ear canals. Usually, click-type sounds are introduced through the earphones, and electrodes measure the hearing nerve's response to the sounds. A computer averages these responses and displays waveforms. Because there are characteristic waveforms for normal hearing in portions of the speech range, a normal ABR can predict fairly well that a baby's hearing is normal in that part of the range. An abnormal ABR may be due to hearing loss, but it may also be due to some medical problems or measurement difficulties."

We should have answers that day, so come back and visit for updates.
