Recalled newborns in the screening for Congenital Adrenal Hyperplasia (CAH) could be due to analytical steroid interferences. Ultra-high pressure liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS) constitutes the gold standard for serum steroid quantification.Objective: To describe the serum profile of a panel of 8 adrenal steroids by UHPLC-MS/MS in recalled infants for CAH.Methods:</st...
