Thyroglobulin (Tg) is a protein produced exclusively by thyroid follicular cells. It serves as a sensitive serum tumor marker to detect residual or recurrent disease in patients who have undergone total thyroidectomy for differentiated thyroid cancer (papillary or follicular). Also helpful in distinguishing thyroiditis from factitious thyrotoxicosis. Specimen: 1x 6ml Plain / SST tube.
