Thyroglobulin Antibody and Thyroglobulin, IMA or LC/MS-MS

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. This helps doctors track the effectiveness of treatment and identify potential cancer recurrence. However, this test cannot determine the exact location of the tissue or diagnose the specific type of disease without further medical evaluation.
