Episode notes
PKU Saved By Early Screening
- Jessica's newborn Max tested positive for PKU on standard newborn screening at 24 hours old and required immediate dietary management.
- Early detection through the heel-prick test allowed Max to thrive and avoid severe developmental harm.
A Drop Of Blood Holds Vast Data
- A single dried blood spot contains enormous diagnostic potential that has grown with technological advances.
- Whole genome sequencing will massively expand what we can screen from that tiny sample.
RUSP Standardizes Newborn Screening
- The Recommended Uniform Screening Panel (RUSP) standardizes a minimal set of disorders across U.S. states to improve equity.
- RUSP currently lists 38 core and 26 secondary disorders but states ultimately decide their panels.
