SandraHi,
I want to clarify that you said his 17ohp was at 13?!? What measurement is that in? The normal range for a CAH child is much higher than 13! Is that 13ng/dl? That would mean that your son is way way over suppressed. The range for a CAH child can be from 200ng/dl to 1000 ng/dl although I have heard that it is now closer to 300 to 900ng/dl. So, please check and let me know.
Sandra
