Test Code Newborn Sc State Newborn Screen

Important Note

The State Newborn Screen includes "expanded NBS" by tandem mass spectrometry and tests for the conditions listed on the requistion link.  Blood collection cards are supplied by the Lab or by unit coordinators in the inpatient floors.

Method is affected by diet, moisture absorbed by the card, improper collection, or being placed in a plastic bag. The sample will be automatically rejected if it is QNS, if a QNS sample has been "added to" (filled from different blood draws) or if it is in a plastic bag. A Children's Lab requisition must accompany the sample.
