Better late than never, I finally got my 17 OHP levels from my endo, which which have ranged from 417-930 while I’ve been on 60mg. hyrdrocortisone over the last 5 years.  When I was previously on 30mg. daily, my level was 3203, which precipitated the increase in my cortisone dose (to bring it down).  Please keep in mind, weight, age, and gender should be factored in when comparing dose and levels.  Take care, Eric
