Wisconsin Metabolic Newborn Screening Program Guide

What is the Wisconsin Newborn Screen?

A critical public health program that identifies potentially life-threatening conditions in newborns through early screening and intervention. The program's success relies on seamless coordination between the Wisconsin State Lab of Hygiene, primary care providers, and specialist consultants. Positive metabolic newborn screens are handled by metabolic specialists at Children's Wisconsin and Waisman Center/University of Wisconsin. Other disease categories reported on newborn screening follow different protocols and are managed by different specialists.

Metabolic Newborn Screen Result Protocol

For Positive Metabolic Results

You should receive two communications:

  1. Initial contact from the Wisconsin State Lab of Hygiene Newborn Screen Program who will convey the positive NBS results
  2. Same-day contact from a metabolic specialist who will make recommendations for patient care and confirmatory testing

For Borderline Results

  • Not considered a positive result
  • You will not be contacted by the state lab; "Borderline" is indicated on the newborn screen report you will receive
  • You will not be contacted by a metabolic specialist and no confirmatory testing is needed
  • Typically requires only a repeat newborn screen within a specified timeframe, indicated on the newborn screen report
