CQ50. Is Serum Thyroglobulin Measurement Useful as a Marker of Carcinoma Recurrence After Surgery?
Thyroglobulin is a chief constituent of colloid in the thyroid follicles, which is vital for the synthesis of thyroid hormone. The serum thyroglobulin level of healthy people is around 30 ng/ml, but it decreases to nearly zero when thyroid tissue does not remain after total thyroidectomy. Whether thyroglobulin measurement is useful as a marker of recurrence after surgery for differentiated carcinoma is examined.
