Thyroxine Binding Globulin
Thyroxine Binding Globulin is a clinical biomarker on the Thyroid panel, reported in µg/mL. Standard reference range: 13–39 µg/mL. Functional (optimal) range used by integrative practitioners: 21–31 µg/mL.
What is Thyroxine Binding Globulin?
Thyroxine-binding globulin (TBG) is the primary transport protein for thyroid hormones; its level affects total T4 and T3 measurements without necessarily reflecting thyroid dysfunction.
Reference ranges
| Range type | Value (µg/mL) | Source |
|---|---|---|
| Standard (lab) | 13–39 | Typical Quest / LabCorp adult reference |
| Functional (optimal) | 21–31 | Integrative / functional medicine consensus |
How SomaVue interprets Thyroxine Binding Globulin
SomaVue maps every result for Thyroxine Binding Globulin 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.
