Possible Non-classical Adrenal Hyperplasia

My daughter saw the Geneticists today and we told him about her 2.1 Cortisol level and her last hospitalization.  She had previously been diagnosed with Cyclic Vomiting Syndrome and just recently PCOS.  During this past hosp. stay, they checked her Cortisol level and when it came back at 2.1 the proceeded with  a Cortisol Blood Stimulation test that they said was normal even though her baseline didn't double.  The dr. we saw today said we need her to see a really, really, really good Endocrinologist.  He said she needs to be tested for 17-hydroxyprogesterone, androstenedione, and testosterone.  Also needs an ACTH stim. test.  Is the Cortisol Blood Stim test different from the ACTH Stim test?  He feels she may have Non-Classical Adrenal Hyperplasia.
