Reverse T3

Reverse T3 is a clinical biomarker on the Thyroid panel, reported in ng/dL. Standard reference range: 9.2–24.1 ng/dL. Functional (optimal) range used by integrative practitioners: 13.2–20 ng/dL.

What is Reverse T3?

Reverse T3 (rT3) is an inactive isomer of T3 produced from T4 under conditions of physiological stress; elevated rT3 may competitively inhibit active T3 binding at cellular receptors.

How SomaVue interprets Reverse T3

SomaVue maps every result for Reverse T3 against four clinical lenses — nutrient cofactors, toxin exposure, infection drivers, and circadian/hormonal context — and connects each interpretation to specific peer-reviewed citations. Pre-mapped clinical reasoning and cross-marker pattern detection are available inside the practitioner workspace.
