My wifes TSH level is 8, but her FT3 and FT4 levels are normal. Is this considered hypothyroidism? What treatment should she follow? I read online that it could be subclinical hypothyroidism, and some sources mention doing an antibody test. Should we get that test done too?
Based on the high TSH level and normal FT3 and FT4 levels, it is likely that your wife has subclinical hypothyroidism. The treatment for this condition typically involves taking Levothyroxine. The usual starting dose for Levothyroxine in adults with subclinical hypothyroidism is 25-50 mcg per day. It is important to follow up with regular blood tests to monitor thyroid function and adjust the dosage as needed.
