10. 17-hydroxyprogesterone > 250 ng/dl, which suggests the possibility of congenital adrenal hyperplasia (if postmenarcheal, the 17-hydroxyprogesterone will be collected during the follicular phase, or >60 if oligomenorrheic). NOTE: If a 17-hydroxyprogesterone > 250 ng/dl is confirmed on repeat testing, an ACTH stimulated 17-hydroxyprogesterone < 1000 ng/dl will be required for study participation
