You would need a minimum of TSH, Free T3 and Free T4, to begin with, to check thyroid function; along with a
Thyroid Stimulating Immunoglobulin (TSI) to confirm/rule out
Graves Disease, which is an autoimmune disease which causes hyperthyroidism and eventually destroys the thyroid gland.
If you can get those tests done, please obtain a copy of the lab report and post the results here, along with the lab's reference ranges, since these vary from lab to lab.
