About Reverse T3 Test | rT3 Testing in Dover
Reverse T3 is a biologically inactive isomer of T3, produced when the body diverts thyroxine (T4) away from active T3 conversion.
Under normal conditions, most T4 is converted to active T3, while a smaller fraction becomes reverse T3. During illness, starvation, or severe stress, this balance can shift, raising reverse T3 levels while active T3 falls.
Because reverse T3 itself does not stimulate thyroid hormone receptors, elevated values do not indicate hyperthyroidism. Instead, they may accompany nonthyroidal illness syndrome, sometimes called sick euthyroid syndrome.
Clinicians use reverse T3 results with TSH, free T4, and total or free T3 to assess whether symptoms or abnormal thyroid values reflect true thyroid disease or another physiological state.
