T3 (liothyronine) uptake and T4 thyroxine and free T4 index are normal, but TSH is4.65 and per the lab that is high. The highest normal is 4.5. What does this mean?

Subclinical. Lab results are consistent with a diagnosis of subclinical hypothyroidism representing very mild and early case of hypothyroidism. I would recommend repeating your blood test first. If these results are confirmed many doctors would recommend thyroid replacement although there is some controversy about the need for treatment.

If (+) closer monitoring, if (-) less close f/u. Fam Hx also important. Don't worry! Read more...

Thyroid tests. All else being equal it means your dose of levothyroxine is probably too high. The TSH level is very low, meaning your body is trying to reduce thyroid hormone levels. Follow-up with your doctor to discuss. Read more...
