According to the laboratory that does my son's tests the following results are considered "normal".  Keep in mind that different endocrinologists may have different ideas about what range they think is normal (or desirable) for a child with CAH and different labs may have different ranges for normal.  My lab reports results as ng/mL, which I believe is equal to ng/dL divided by 100 (please correct me anyone if this is wrong).

17-Hydroxyprogesterone:

3 days-2months: 0.1 - 9.40 ng/mL   (or 10 - 940 ng/dL)

3 months - 11 yrs: nd - 0.90 ng/mL  (or nd - 90 ng/dL)

Androstenidione:

Children:  0.1 -
