I'm glad you're taking her in....having her tested is the only way to find out if she has CAH. Do you notice any other symptoms? Our daughter is classic, non-salt-wasting..and we didn't find out until she was almost 4 yrs old. (She falls under the "classic" category in that she has the simple virilizing form of CAH--clitoromegaly, pubic hair, and increased 17-OHP levels). From what I've read and heard, I believe siblings from the same family can have different 'combinations' of this disorder: severe salt-wasting, mild non-SW, etc. Good luck..and let us know what happens.
