Newborn screening

Screening tests help your doctor look for a certain disease or condition before any symptoms appear. All states require newborn screening, although the tests required vary from state to state. They may include:

• Bilirubin test (to test for jaundice).
• Congenital heart disease test.
• Galactosemia test.
• Hearing test.
• Phenylketonuria (PKU) screen.
• Sickle cell disease test.
• Thyroid hormone tests (for thyroid problems that are present at birth).

This test is done to find out whether your baby has certain diseases that could eventually cause problems. When discovered early, these diseases can be treated to improve the child's health.

A heel stick is used to get a blood sample from a baby. The baby's heel is poked, and several drops of blood are collected. Your baby may have a tiny bruise where the heel was poked.

Small soft sensors are placed on your baby's hand and foot to check oxygen in the blood.

Soft headphones are used on or near the baby's ears. Tones or clicks are used to test for a hearing response. Sometimes small electrodes are placed on the baby's head.

In general, you don't need to prepare your baby for this test.

If the test result is abnormal, remember that this is only a screening test. An abnormal result only means that further testing is needed.
