Indicator Explainer
Thyroglobulin
Thyroglobulin (2768 aa, ~305 kDa) is encoded by the human TG gene. This protein is involved in thyroid hormone synthesis.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
