Blood Test: This basic screening test is also called as a heel test. In this, the baby’s heel is pricked and the small blood droplets are then placed on a filter paper card. This is then sent for an analysis.
Physical Check-up: In the physical assessment, the baby’s heartbeat, eyes, and other organs and functioning are checked. This is done within 72 hours after the baby is born and then a further detailed assessment is done when your baby is about six to eight weeks old. This assessment gives an idea whether the child has any such conditions which need advanced screening. The second check-up or assessment is done to rule out any issues as at times, it could take some time for certain conditions and symptoms to develop.
Pulse Oximetry Test: This is done to check the blood oxygen levels. In case the baby has lower blood oxygen level, it could mean that she could have some heart problem. There’s a small equipment called a pulse oximeter, that is used long with a sensor on your baby’s skin. It’s a painless and non-invasive test and is done within 24 hours of baby’s birth.
Hearing Test: The baby’s hearing ability is also checked in these tests. These checks take about 5 to 10 minutes and the best part is that these tests can be done even when your little one is sleeping. There are two tests which are conducted:
Auditory brain stem response: This test is done to check how your child’s brain responds to certain sound and how it analyses the auditory brain stem. Very small earphones are put into the baby’s ears and then some sounds are played. Tiny electrodes are placed on the head to determine how the baby’s brain is reacting to every sound that is played. In case the response is not consistent, it could mean that your baby has some hearing problem.
Otoacoustics emission test: This test checks different parts inside baby’s ear and uses very small earphones and a tiny microphone that is placed inside the ear. Different sounds are then played and the attached microphone detects various echoes. If the child’s hearing is normal, the played sounds would generate echoes in the ear canal. But in case it doesn’t and none of these sounds are picked up, it could mean a loss of hearing.
