Order Reverse T3 Test | rT3 TestingThe Reverse T3 test measures the level of reverse triiodothyronine, a biologically inactive form of thyroid hormone, in the blood. It is typically ordered alongside other thyroid function tests to help clarify unusual thyroid hormone patterns, particularly when standard results do not match a person's clinical picture.
About Reverse T3 Test | rT3 Testing in Norwich
Reverse T3 is produced when the body diverts thyroxine (T4) away from forming the active hormone T3.
Under normal conditions, most T4 is converted to T3, the hormone that acts on cells to regulate metabolism. A smaller portion is converted to reverse T3, which does not stimulate thyroid hormone receptors and is considered metabolically inactive.
In states of severe illness, starvation, major surgery, or significant physical stress, the body can shift conversion toward reverse T3 and away from T3. This adaptation conserves energy during acute threats but can produce thyroid test results that mimic hypothyroidism even when the thyroid gland itself is functioning.
Because reverse T3 alone cannot diagnose a specific condition, it is interpreted with thyroid-stimulating hormone (TSH), free T4, total T4, and total T3. This combination helps distinguish nonthyroidal illness syndrome from primary thyroid disorders and guides whether further evaluation is warranted.
