A complete thyroid panel can tell you about thyroid function, feedback loops, and how thyroid hormones are converting. The main thyroid markers are TSH, the pituitary hormone-stimulating gland, and T4 and T3, which are produced by the thyroid gland. Thyroid hormones are bound to proteins called thyroid hormone-binding globulins. Those are total T4 and total T3. T4 is converted to T3, which also makes reverse T3. At some point, thyroid-binding globulin levels release the T3 and T4, which then become free T3 and free T4. You can have defects all along these pathways, which I discuss in this podcast.
