Worried! Thyroid lab test came back normal tsh, freet4, tg panel, tg antiboby, tpo, but had a scan came back overative thyroid. What does it mean.

Serval, It is a false positive. You are healthy. The iodine uptake and scan might be high for other reasons, iodine depleation being one of them. We do not treat the test, we treat you.
Not helpful. A thyroid uptake and scan uses radio-labeled iodine to detect how much iodine the thyroid is using. Iodine is necessary for thyroid hormone production. There is no utility, however, in obtaining an uptake and scan unless you have biochemical evidence of hyperthyroidism (low tsh, high ft4/ft3).
