CAH 3 BETA

Assallam O Alaekum, My son is 3 beta CAH and he is on drugs of florinef and hydrocortisone. I want to know about 17OHP test. Before his treatment this 17OHP test results came high so could anyone tell me that now he is on drugs since birth and 10months old now so what would be his 17OHP test results with the drugs? High or normal range. Thanks
