THYROGLOBULIN (TG)
What does THYROGLOBULIN (TG) measure?
The thyroglobulin (TG) test measures the level of thyroglobulin, a protein made by thyroid tissue, in the body. It may be used to help monitor people who have been treated for certain types of thyroid cancer, particularly after thyroid removal or radioiodine treatment, as changes in levels can provide useful follow-up information. Results are interpreted alongside medical history, imaging, thyroid-related tests, and possible thyroglobulin antibody testing.
