A 24-year-old female asked:

everything including lh/fsh ratio, dhea, testosterone normal, but 17-oh came back 366 (luteal phase) the limit is around 469, is this late onset cah?

Probably not: The most common form of cah is due to 21 hydroxylase deficiency resulting in high 17 ohp levels. The level should be done in the follicular phase of the cycle, and if above 200 would be abnormal. One can confirm the diagnosis by doing a Cortrosyn stim test, measuring cortisol and 17 ohp before and 1 hr after receiving cortrosyn. High 17 ohp during the luteal phase is not specific for a diagnosis.

Also very unlikely to have CAH when DHEAS is normal.

With the level only minimally elevated, CAH is unlikely. The ACTH (cortrosyn) stimulation test is a good idea to be certain.
