I'm really worried about my wife's thyroid levels. Her TSH level came back as 8, which seems high, but her FT3 and FT4 are normal. Does this mean she has hypothyroidism? I looked it up and found something about subclinical hypothyroidism and a test for antibodies. Should we consider doing that test? What would be the right treatment for this situation?
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.
