Thyroglobulin and Thyroglobulin Antibody Panel
A thyroid-cancer monitoring marker paired with the antibody that can throw off its reading.
Consider this test if:
- Monitoring for residual or recurrent thyroid cancer after thyroidectomy or radioactive iodine ablation
- Tracking thyroglobulin over time and needing the antibody result to confirm the value is reliable
- Working up suspected autoimmune thyroid disease such as Hashimoto's
- Establishing a post-treatment baseline to compare future thyroglobulin results against
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required. If you are being monitored after thyroid cancer treatment, the timing relative to your therapy and TSH status affects interpretation, so follow your care team's schedule and try to test under consistent conditions for comparable results over time.

What members say on Trustpilot
What this test is for
Thyroglobulin is a protein made only by the thyroid gland, which makes it a useful marker for tracking well-differentiated thyroid cancer after the thyroid has been removed or ablated: a rising level can signal residual or recurrent disease. This panel pairs it with thyroglobulin antibodies, which matter for two reasons. The antibodies are present in most people with autoimmune thyroid disease such as Hashimoto's, and they also interfere with the thyroglobulin assay, typically pushing the thyroglobulin result inappropriately low, so the two are measured together to interpret thyroglobulin correctly. Thyroglobulin is a monitoring tool, not a diagnostic test for thyroid cancer or thyroid function.
If your question is autoimmune thyroid disease rather than cancer surveillance, the thyroglobulin antibody alone, or the TPO and thyroglobulin antibody panel, is usually the more direct choice; this combined panel is built around interpreting the thyroglobulin number.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost — covering the lab and what it takes to run the service — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
