How Is Ncah Diagnosed

How is 21 hydroxylase deficiency diagnosed?

Diagnosis. Routine newborn screening typically includes measuring serum levels of 17-hydroxyprogesterone. If levels are elevated, the diagnosis of 21-hydroxylase deficiency is confirmed by identifying low blood levels of cortisol and by identifying high blood levels of DHEA, androstenedione, and testosterone.

Can CAH go undiagnosed?
