Order Reverse T3 Test | rT3 TestingThe Reverse T3 (rT3) blood test measures a metabolically inactive form of thyroid hormone. It is most often used alongside other thyroid tests to help distinguish true thyroid dysfunction from changes that occur during severe illness or stress.
About Reverse T3 Test | rT3 Testing in Bellevue
Reverse T3 is a mirror image of the active thyroid hormone T3, and it does not stimulate metabolism.
The thyroid gland mainly produces thyroxine (T4), which is converted in peripheral tissues either to active triiodothyronine (T3) or to reverse T3. Under normal conditions, the body favors T3 production, but during illness, starvation, surgery, or significant stress, conversion shifts toward reverse T3.
Because reverse T3 is biologically inactive, a rise in its level can accompany a low T3 state without indicating primary thyroid disease. This pattern is sometimes called nonthyroidal illness syndrome or sick euthyroid syndrome.
The reverse T3 test is typically ordered with T3, free T4, and TSH so that results can be interpreted together. No single value gives a complete picture of thyroid status, and reference ranges vary by laboratory method.
