Blues acth came back 3.5 pre and 3.5 post. (At the bottom of the results the lab stated an extra lavender tube was submitted and would be held for 48 hours). So I'm hoping they did the tests right. Ever see it perfect like that? The same? Last month prior to vetroyl it was 3.0 pre and 28 post. Doctor said keep him on 120mg daily and unless anything changes with him they would test again in 6 months. He weighed in at 95lbs. Last month he was 106lbs. T4 is 1.7 . I asked the doctor about the dosage and how the guidelines from drug maker may have changed to lesser mg per lb recommendations but the doctor stated he was on correct dosage. I also told him I was new to cushings and I am trying to educate myself and I thought I had read where testing should be 30 days rather than 6 months? He felt if blue is doing well then keep doing what we are doing. If he loses weight or gets sick like vomiting diarrhea let them know. I admit I should be jumping for joy I suppose but I also feel this nervous speculation. I guess I'll take one day at a time and hope for the best. Blue is doing better with his symptoms somewhat. Certainly no worse. His skin is looking better and they gave him 3 more weeks of antibiotic and still prescribing thyroid pill as well.
