Newborn Screening

Newborn screening is the practice of testing every newborn for certain harmful or potentially fatal disorders that aren't otherwise apparent at birth. With a simple blood test, doctors often can tell whether newborns have certain conditions that eventually could cause problems. Although these conditions are rare and most babies are given a clean bill of health, early diagnosis and proper treatment sometimes can make the difference between lifelong impairment and healthy development.

When should a second screen be collected?

If your patient is born outside of Delaware, Delaware does not require a second screen to be collected if the FIRST screen is Within Normal Limits. 

Can a family refuse newborn screening? 

Yes. Parents or legal guardians can refuse newborn screening for one or both mandated screens.

The collection facility must fill out the Newborn Screening Refusal Form with parent/legal guardian signature, as well as, completed filter paper card with “Refusal” written across the top and ship BOTH documents to PerkinElmer via UPS. 

A copy of the refusal form should be faxed to the Newborn Screening Program at (302) 295-0719 or emailed to

Which patients will you have access to on Perkin Elmer’s results portal?

When you log in to the Perkin Elmer site, you will have access to any patients you have ordered repeat collections as well as first and second screens for any patients identifying your office as their PCP at any of the Delaware birthing hospitals, centers or home-births via midwifery. 

By unchecking the “include only your practice” box, the portal allows for broader searches for patients who might have had a name or PCP change since the blood spot was collected. 

When searching for patient’s in the portal, best practice is to search by Mother’s last name.

What is the average timeframe for the results of a newborn’s first screen to be accessible in the PerkinElmer portal?

If the screen is collected on day two of life, and shipped to PerkinElmer on day three of life, then final results should be posted by day five of life.
