I have hypothyrodism .. taking eltroxin 100 .. what does it mean to have t3 (liothyronine) and t4 in normal range while having a low tsh ? 0.22

Probably little.: The low TSH value with the others being normal may suggest the hypothyroidism is overtreated. The test works in reverse. Low thyroids have a high level and vice versa. This also can be something called euthyroid sick syndrome. . Review with your doctor and get his/her advice.

Good control!: Those figures sound swell. The normal range for both circulating thyroid hormones plus a low TSH (= Thyroid stimulating hormone) from your pituitary gland the "controller" at the base of your brain means the medication is being given in the correct dose!! Its good news!
