I am posting information my sister P.R. resident, mother of a boy with CAH 21OH - Salt Wasting, relayed to me to post because she does not have access to the internet at the time. My nephew was recently tested twice by his endocrinologist and the results of the test are the following: 17 Hydroxiprogesterone :  0.0 DHEAS Sulfate                :  0.0 Creatinine                           : 0.0 Bun-Creatinine                  : 118 Bone Age: 6 years old hands in a matter of 3 months Sex: Male Age: 4 Weight: 38 lbs. Height: 3 feet He is currently on 12.5 mg of Cortef    (7.5 AM and 5.0 PM) Can anyone help?She is very concerned about this and I would like to help. I would appreciate a response from anyone parents/doctors that may have had experience with this condition or scenario. Thanks, Adeline Figueroa
