The Role of Reverse T3 in Thyroid Function (Part 1)

Reverse T3 measurement is one of the important markers that need to be checked periodically while monitoring the thyroid supplemental hormone (supplementation with T4 or T4/T3 especially). Conventional medicine acknowledges that Reverse T3 concentrations are high in patients with chronic nonthyroidal illnesses due to such causes as hypoxia and impaired conversion of rT3 into T2.

Why TSH is not the Best Marker of Thyroid Function

TSH stands for Thyroid Stimulating Hormone and is produced by the pituitary gland in the brain. The simplistic view of produced hormones looks like this: TRH (Hypothalamus – part of the brain) -> TSH (Pituitary – part of the brain) -> Thyroid hormone Free T4 (Thyroid) -> Conversion of Free T4 to Free T3.

Functional vs Normal Labs

There are two lab ranges that coexist: pathological lab range and functional lab range. The pathological lab ranges are used to diagnose and see the progress of the disease. The functional lab range is used to see the first markers of the disease development. When I see a new patient and I hear “My previous
