Background: The expansion of newborn screening pro-grams has increased the number of newborns diag-nosed with inborn errors of metabolism in the pre-symptomatic phase, but it has also increased the number of costly, stress-producing false-positive results. Be-cause propionylcarnitine (C3) is one of the analytes most frequently responsible for false-positive results, we aimed to develop a rapid liquid chromatography– tandem mass spectrometry (LC-MS/MS) method to identify free methylmalonic (MMA) and 3-OH propi-onic (3OH-PA) acids in blood spots. Methods:We studied newborn screening spots from 250 healthy controls; 124 from infants with abnormal C3, of whom only 5 (4%) were truly affected; 124 from infants with altered isolated methylmalonylc...
