Hi. I have just received the results of my thyroid blood tests back from the lab, but with no advice on what to do now. Up until 3 months ago I was taking 200mcg levothyroxine, which my GP then lowered to 175mcg levothyroxine. Can anyone please tell me what action I should take now. my TSH is a little Low at 0.24 (normal range 0.27 - 4.2) and my Thyroid Peroxidase Antibodies reads 76.4 (very high, normal range is 0 - 34). The NHS tests only show TSH and T4.
