Abstract

False-negative newborn screening data for congenital adrenal hyperplasia are limited and have not included Pennsylvania and New Jersey. Within our program, we identified 16 missed cases of 96 patients born in Pennsylvania and New Jersey between 1998 and 2024, highlighting the need for continued evaluation in clinically suspicious circumstances despite normal screening.
