Order Reverse T3 Test | rT3 TestingThe Reverse T3 (rT3) blood test measures a metabolically inactive form of thyroid hormone. It is used to help determine if an individual has "nonthyroidal illness syndrome" or "sick euthyroid syndrome" as opposed to primary thyroid dysfunction.
About Reverse T3 Test | rT3 Testing in Balch Springs
Reverse T3 is a byproduct of thyroid hormone metabolism, not a hormone produced directly by the thyroid gland.
The thyroid gland primarily produces thyroxine (T4), which is converted in peripheral tissues to either active triiodothyronine (T3) or inactive reverse T3.
Under normal conditions, the body favors T3 production. During severe illness, starvation, or major stress, conversion shifts toward rT3, reducing metabolic activity.
Because rT3 itself does not stimulate metabolism, an elevated level can indicate a nonthyroidal illness rather than a primary thyroid disorder. Results are interpreted alongside other thyroid tests such as TSH, free T4, and total T3.
