Testing Hints for Newborns

1. Do not screen patient more than three times per ear.
Overscreening can result in a false negative result.

2. Swaddle baby and position on side for best access to ear.

3. Test at least 11 hours after birth, if possible, to prevent false
positives due to vernix.

4. If infant fails, re-test at least one more time before discharge.

5. If one ear fails, try to have baby lay so that the failed ear is
facing up for a while to clear vernix before retesting.

6. If infant is fussy or crying, offer pacifier.

7. OK to test while infant is nursing.
