STTM Reverse T3 and Free T3 Thyroid Function

Why is this test important? HealthCheckUSA has partnered directly with Janie Bowthorpe and others at Stop the Thyroid Madness to develop specific packages and test options that will assist Stop the Thyroid Madness members in managing their condition and taking control of their health.The STTM Reverse T3 and Free T3 Thyroid Function Panel is a group of blood tests that help evaluate thyroid gland function and to help diagnose thyroid disorders. The thyroid tests included in a thyroid profile measure the amount of thyroid hormones in your blood. These hormones are chemical substances that travel through the bloodstream and control or regulate your body's metabolism—how it functions and uses energy.

When the body is under stress, instead of converting T4 into T3 - the active form of thyroid hormone - the body conserves energy by making what is known as Reverse T3 (RT3), an inactive form of the T3 hormone. The value of RT3 tests in diagnosis is controversial, as some practitioners believe that the body continues to manufacture RT3 instead of active T3, causing various symptoms that are identified as the so-called "Wilson's syndrome."

Free T3 measures the free, unbound levels of triiodothyronine in your bloodstream. T3 is the active thyroid hormone, also called triiodothyronine, and can be the most important lab you will do. Free T3 is considered more accurate than Total T3. Free T3 is typically elevated in hyperthyroidism, and lowered in hypothyroidism.
