Order Reverse T3 Test | rT3 TestingReverse T3 testing measures a form of thyroid hormone that the body produces but does not use in the same way as active thyroid hormone. Because rT3 can rise when the body is under stress or illness, it is often ordered alongside standard thyroid tests to give a fuller picture of thyroid function.
About Reverse T3 Test | rT3 Testing in Kent
Reverse T3 is a biologically inactive isomer of triiodothyronine (T3), created when the body diverts T4 away from producing active T3.
Under normal conditions, the thyroid gland produces mostly thyroxine (T4), which is converted in peripheral tissues to T3, the hormone that drives metabolism at the cellular level. A portion of T4 is instead converted to reverse T3, which binds to thyroid receptors without activating them.
Reverse T3 levels often increase during acute or chronic illness, surgery, starvation, and other forms of physical stress. In these states, the body appears to shift T4 metabolism toward rT3 production, reducing energy expenditure. This pattern is sometimes described as nonthyroidal illness syndrome or sick euthyroid syndrome.
Because rT3 alone cannot confirm or exclude a thyroid disorder, it is typically interpreted with TSH, free T4, free T3, and sometimes thyroid antibodies. A clinician uses the overall pattern, along with symptoms and medical history, to decide whether further evaluation or treatment is appropriate.
