My son is 10 mo. old and he has CAH salt-wasting. I'll share the info that I was given, but I have noticed other messages mention 17 OHP levels that are very different than my son's range. I wonder if there are different ways to measure the levels and therefore different ranges. For what it is worth - here are the ranges I was given for kids 2 months to 11 years old: Sodium 137 - 147 Potassium 4.1 - 5.3 17 OHP 0 - .98 Androstendione 0 - .5 Beginning in May we are going to a different endo. She tests Sodium, Potassium, 17 OHP and ACTH. I know many people have renin tested, but for some reason the endos I've talked to in this area don't test that. Hope that helps. I know I get nagging feelings alot about my son's treatment. I find it difficult because I keep learning new things about CAH treatment and it is hard not to feel like there is something else new I am missing. Thank you for posting this message. It will be very interesting to see what other dr.s have told people. Take care.
