Thyroglobulin level with thyroglobulin antibodies from one draw — the pair used to monitor after thyroid cancer treatment and to evaluate thyroiditis. Thyroglobulin is a protein made only by thyroid tissue, so after the thyroid has been removed or ablated for thyroid cancer, a rising or detectable thyroglobulin is the earliest signal that thyroid cells remain or have returned; endocrinologists follow it at regular intervals for years. The antibody measurement is run at the same time because thyroglobulin antibodies interfere with the thyroglobulin assay — when they are present the thyroglobulin value can read falsely low, and the antibody level itself becomes the marker that is followed. Outside cancer care, thyroglobulin is raised in thyroiditis, Graves' disease and goiter, and it is sometimes measured to tell factitious hyperthyroidism (taking thyroid hormone) from thyroid overactivity, since thyroglobulin is suppressed in the former. This panel reports both values separately. Results should be interpreted by the clinician managing your thyroid care, ideally with the same laboratory used for previous measurements, because thyroglobulin assays differ between labs. ## Biomarkers measured - Thyroglobulin - [Thyroglobulin Antibodies](https://www.test-well.com/biomarkers/thyroglobulin-antibodies) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $39.99 | $45.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $34.99 | $40.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.

A Thyroglobulin Panel (Thyroglobulin + Antibodies) test costs $39.99 at TestWell — $45.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $250.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible. | Where you order | Price | One test, all-in | Notes | | --- | --- | --- | --- | | TestWell (drawn at Quest or Labcorp) | $39.99 | $45.99 | Includes the one $6 lab processing fee, charged once per order | | Hospital outpatient lab, self-pay (typical) | $250.00 | $250.00 | Reference figure; hospital charges vary widely by facility and are often higher | Lab test codes: Quest test code 30278 · BioReference code 7470-8. ## How do you prepare? No fasting required. Stop high-dose biotin supplements at least 2 days before the draw. Tell your clinician if you have had thyroid surgery or radioactive iodine — it changes how the result is read. ## How to order 1.
