Order Reverse T3 Test | rT3 TestingReverse T3 is a thyroid hormone produced when the body diverts thyroxine (T4) away from the more active triiodothyronine (T3). While T3 drives cellular metabolism, reverse T3 is largely inactive, and its level can rise during illness, stress, or calorie restriction. This test measures the amount of reverse T3 circulating in the blood.
About Reverse T3 Test | rT3 Testing in Omaha
Reverse T3 testing is typically ordered alongside other thyroid tests to give a fuller picture of thyroid hormone metabolism.
Thyroid function is often assessed with TSH, free T4, and free T3. Reverse T3 adds information about how the body is converting T4, since T4 can be routed toward either active T3 or inactive reverse T3.
In nonthyroidal illness syndrome, sometimes called sick euthyroid syndrome, reverse T3 can be elevated while TSH and free T4 remain within or below their usual ranges. This pattern can occur with acute or chronic illness, major surgery, trauma, starvation, or significant physiologic stress.
Because reverse T3 alone does not diagnose a specific condition, results are interpreted with the other thyroid values, the clinical context, and the individual's symptoms. A single elevated reverse T3 level does not by itself confirm or exclude thyroid disease.
