Used in research settings to quantitatively measure human thyroglobulin levels in serum or plasma samples. This assay is particularly valuable in monitoring patients with thyroid cancer, especially after thyroidectomy, to detect recurrence or persistence of disease. It supports studies on thyroid function, autoimmune thyroid disorders, and the effectiveness of therapeutic interventions. The kit enables high-throughput analysis with high sensitivity and specificity, making it a reliable tool in clinical research and laboratory investigations involving thyroid-related biomarkers.
