Combined Gestational Age- and Birth Weight–Adjusted Cutoffs for Newborn Screening of Congenital Adrenal Hyperplasia

The use of cutoff values adjusted for both GA and BW significantly reduced FP rates (0.03%) and increased overall PPV (16.5%). Based on our 10 years of experience, we recommend the implementation of this two parameter-adjusted approach for NBS of classic CAH in NBS programs worldwide.
