Order Reverse T3 Test | rT3 TestingThe Reverse T3 test measures the level of reverse triiodothyronine (rT3) in the blood. This test is typically used to investigate whether an individual has nonthyroidal illness syndrome or sick euthyroid syndrome, rather than a primary thyroid disorder. By evaluating rT3 alongside other thyroid hormones, healthcare providers can better understand how the body is converting thyroid hormones.
About Reverse T3 Test | rT3 Testing in Plantation
Reverse T3 is an inactive form of thyroid hormone produced from thyroxine (T4).
Under normal conditions, the body converts T4 into active T3 or inactive rT3. In certain illnesses or severe stress, this conversion shifts toward increased rT3 production, which can lead to low T3 levels and symptoms that resemble hypothyroidism.
The Reverse T3 test helps differentiate between true hypothyroidism and nonthyroidal illness syndrome, where thyroid hormone levels may appear abnormal due to an underlying condition rather than a thyroid problem.
Results are usually interpreted alongside T3, T4, and TSH levels. A high rT3 level may suggest that the body is preferentially producing inactive hormone, often in response to illness, starvation, or major surgery.
