THYROGLOBULIN ANTIBODY (A-TG)

The THYROGLOBULIN ANTIBODY (A-TG) test measures circulating autoantibodies directed against thyroglobulin, a protein produced by the thyroid gland. Detection and quantification of anti‑thyroglobulin antibodies help identify autoimmune thyroid conditions (for example, Hashimoto’s thyroiditis and some cases of Graves’ disease) and can influence interpretation of thyroglobulin tumor markers used in differentiated thyroid cancer follow-up.

This service is offered as a Dubai at‑home blood collection, where a licensed phlebotomist collects a venous sample for laboratory analysis. Results are reported quantitatively, allowing clinicians to monitor trends over time; positive or rising anti‑Tg titres suggest autoimmune activity or assay interference and should be interpreted alongside TSH, free T4, clinical findings, and—when relevant—serum thyroglobulin levels. Always review results with your treating physician or an endocrinologist for appropriate management in the UAE context.
