What is the difference between the screening that was done in the hospital and diagnostic tests that are needed? 
The screening that was done in the hospital or birthing center was just a screening. Screenings are a way of identifying the need for further testing. 

How will my baby’s hearing be tested? 
Every complete hearing test for babies should include an 
ABR (Auditory Brainstem Response). This test measures 


Guam EHDI Project 
How well the baby’s ears and nerves respond to sound. An ABR is done while your baby is sleeping. 
A special ticker is placed on the forehead, and sounds are played into each ear through a small microphone. The responses of your baby’s ears and nerves are detected and recorded in a computer. 
The testing takes several hours to complete, and it gives comprehensive information about your baby’s ability to hear.
