Hi from Australia! I read with interest the messages re: 17 ohp levels. I have a 2 year daughter who has classic CAH and have just received her biochemistry back showing that her 17 ohp level had risen from a level of 20 in May to a level of 104 at the end of July. Her endo has written to me saying that she is "growing out of her hydrocortisone" dose and to increase to 4mg morning, 2mg afternoon and 4mg evening with the fludrocortisone to remain the same. Has anybody established yet what the normal 17 ohp level is? Also this board is a wonderful help! I am living in country Western Australia and don't feel so isolated with all this information at my fingertips - Thanks
