I'd be grateful for some comments and advise on these results from Blue Horizon, please. I currently take 100mg levothyroxine and my GP has been trying to keep my TSH level at 1 (lower than the range recommended by the lab here). I feel about 80% better than prior to my diagnosis last summer, but still feel unwell and am depressed by my very rapid weight gain (4stone over 2 years). The Blue Horizon doctors comment says "The thyroid function is currently normal. The positive thyroid antibody result, however, increases the possibility of your having autoimmune thyroid disease, such as Hashimoto's thyroiditis or Grave's disease."
