Thyroid scan/uptake shows mild hyperthyroidism, blood-work shows hypothyroidism. What's up with that?

In brief: Labs are right

Thyroid scan/uptake shows how active someone's thyroid is in trapping iodine, but not whether or not their thyroid is able to convert iodide to iodine and make thyroid hormone with it.
In this situation, the labs tell the true story - that the thyroid can't make enough thyroid hormone. Uptakes and scans are morehelpful in people with hyperthyroidism, and don't add much info in hypothyroidism.

In brief: Thyroiid scan unhelp

Thryroid scans do not help with hormonal status of the gland.
