If 17-OHP is above 300 ng/ml, ACTH stimulation test is performed. 0.25 mg of cortrosynim is given. 0 and 1 hour 17-OHP values ​​are measured. Values ​​above 1000 ng/ml suggest congenital adrenal hyperplasia and genetic tests are performed.

If total testosterone is above 150 ng/dL or DHEAS 600 mcg/dL, evaluation for adrenal gland tumor should be made.
