T3 Uptake
T3 Uptake is a clinical biomarker on the Thyroid panel, reported in %. Standard reference range: 24–39 %. Functional (optimal) range used by integrative practitioners: 29–35 %.
What is T3 Uptake?
T3 uptake (resin uptake) is an indirect measure of unoccupied thyroid hormone binding sites on TBG; it adjusts total T4 interpretation when TBG levels are abnormal.
Reference ranges
| Range type | Value (%) | Source |
|---|---|---|
| Standard (lab) | 24–39 | Typical Quest / LabCorp adult reference |
| Functional (optimal) | 29–35 | Integrative / functional medicine consensus |
How SomaVue interprets T3 Uptake
SomaVue maps every result for T3 Uptake 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.
