Thanks for the reply - my daughters labs are done every 3 months, unfortunately I don't get to see the results for myself and I do not know how it is measured. I will have to try and get hold of the endo and find out more. As far as I know the androstine is not done - another thing to find out! The sooner the better as we have just come out of yet another stay in hospital, unfortunately I have to rely on my local doctor who is not upto date with CAH and our endo by phone when we can get him! We shall persevere.
