My TPO antibodies went way down to >6, and my TG antibodies went down to 1.5, then crept up to 1.9. The TPO's didn't move. I slacked off on the selenium from 400 a day down to 200 a day. I am going back up to 400 selenium, and upping my Iodine to 50 for a week and then 100mg for about 6 weeks, then do another blood test and see where I land. Wondering if the lower selenium dose allowed for the rise in TGab's?
