What are the reference ranges for the FT3 and FT4? Reference ranges vary lab to lab, so must come from your own lab report.
Typically, when one has hyperthyroidism, TSH is very low, while FT3 is higher than normal. TSH (Thyroid Stimulating Hormone) is a pituitary hormone, which, ideally, stimulates the thyroid to produce T4 and T3. When there's adequate thyroid hormones, the pituitary slows down or stops putting out TSH. High levels of FT3 will, cause this to happen. This can also happen if you are taking a replacement thyroid hormone and are over medicated.
Have you been diagnosed with a thyroid condition? Are you on a thyroid medication of any kind, whether replacement hormones or anti-thyroid med?
You should get tested for thyroid antibodies, for both Hashimoto's Thyroiditis and Graved Disease.
