Thyroglobulin Antibody and Thyroglobulin, IMA or LC/MS-MS Labcorp test 042045

This test measures the level of thyroglobulin, a protein produced by thyroid cells, along with antibodies that interact with it. It is primarily used to monitor patients who have had their thyroid gland removed, as detecting this protein often indicates that thyroid tissue or cancer cells are still present or have returned.
