Order Reverse T3 Test | rT3 TestingThe Reverse T3 (rT3) test measures a metabolically inactive form of thyroid hormone in the bloodstream. It is typically ordered alongside other thyroid tests to help distinguish between true thyroid dysfunction and changes in thyroid hormone metabolism caused by acute or chronic illness.
About Reverse T3 Test | rT3 Testing in Chesapeake
Reverse T3 is a biologically inactive isomer of triiodothyronine (T3), produced when the body diverts thyroxine (T4) away from active T3 production.
Under normal conditions, most T4 is converted to active T3, which regulates metabolism, heart rate, and body temperature. In states of severe illness, starvation, or major stress, the body shifts conversion toward reverse T3, which binds to thyroid receptors without activating them.
This shift can produce laboratory results that mimic hypothyroidism—low T3 and sometimes low T4—even when the thyroid gland itself is functioning normally. Clinicians refer to this pattern as nonthyroidal illness syndrome or sick euthyroid syndrome.
Measuring reverse T3 alongside TSH, free T4, and total or free T3 helps clarify whether abnormal thyroid hormone levels reflect primary thyroid disease or an adaptive response to another medical condition. The test requires a standard blood draw, and results are typically available within one to three business days.
