Newborn Screening

What is newborn screening?

Newborn screening is an important health test done in every U.S. state and in many other countries. It helps find certain genetic and metabolic disorders that are difficult to diagnose by looking at a baby and easy to fix if detected early. Finding these conditions early can help prevent serious health problems as the baby grows. 

How and when is the screening done?

Newborn screening involves two blood tests in which a few drops of blood are taken from your baby’s heel and placed on special paper for testing. Your infant may feel a little discomfort during the test, but the area will heal quickly. You can help comfort your infant by feeding, rocking, or swaddling them afterward.

The first test is collected at the hospital when your baby is about 18-24 hours old. The second test, which can identify conditions involving digestion, is recommended when your baby is 7-14 days old. This second test is collected during your baby’s Well Care Check-up at Allegro Pediatrics.

How will I get my baby’s results?

Your pediatrician at Allegro Pediatrics will receive the results a few weeks after the test. Most results are normal and will be discussed at your baby’s 1 month Well Care Check-up. If the results are not normal, our office will call you to discuss confirmation testing or follow-up care.

Can I refuse?

Newborn screening is required by law in Washington State, and most parents choose to participate to help safeguard their baby's health. However, parents may decline the screening for religious reasons. If you choose not to proceed with testing, your birth hospital will ask you to sign a form acknowledging your decision and understanding of potential risks. Without screening, some serious health conditions may not be detected early, which could delay treatment and impact your baby’s well-being.
