THYROID PANEL COMPREHENSIVE (FT3, FT4, TSH, TGA ABS, TPO ABS, RT3)

THYROID PANEL (includes: T3 Uptake, T4 (Thyroxine) Total, Free T4 Index)

The thyroid panel is used to see how well the thyroid gland is functioning. The thyroid is responsible for producing hormones that are important for many bodily processes. Abnormal thyroid function, such as underactive thyroid (hypothyroidism) or overactive thyroid (hyperthyroidism), can lead to a wide range of symptoms. By measuring levels of thyroid hormones in the blood, the thyroid panel can help diagnose thyroid disorders and disrupted thyroid function.

A thyroid panel can also be used to monitor the treatment of hyperthyroidism and assess patients receiving levothyroxine therapy. Levothyroxine therapy replaces or supplements thyroid hormones that are reduced or absent due to hypothyroidism, thyroid cancer, thyroid nodules, and goiters.

The thyroid panel uses one blood sample to test for multiple elements related to thyroid function. Specifically, it measures the amounts of thyroid hormones and thyroid-stimulating hormones in the body.

Three hormones are part of a standard thyroid panel:

TSH (thyroid-stimulating hormone)
Free T4 (thyroxine)
Free T3 or total T3 (triiodothyronine)
