About Reverse T3 Test | rT3 Testing in Ann Arbor
Reverse T3 testing is typically ordered alongside other thyroid markers to evaluate how the body is converting thyroid hormones.
The thyroid gland produces mostly thyroxine (T4), which is converted in peripheral tissues either to active triiodothyronine (T3) or to reverse T3 (rT3), an inactive form. Under normal conditions, the body balances these pathways.
In states of acute or chronic illness, severe stress, starvation, or major surgery, conversion may shift toward greater rT3 production and reduced active T3. This pattern is often described as nonthyroidal illness syndrome or sick euthyroid syndrome.
Because rT3 alone does not diagnose a specific condition, it is interpreted with TSH, free T4, total T3, and sometimes free T3. Results can help distinguish true thyroid dysfunction from altered hormone metabolism related to another illness.
