Thyroid antibody tests detect antibodies that attack the thyroid gland, which is the hallmark of autoimmune thyroid diseases. This includes TPO antibodies (associated with Hashimoto's thyroiditis) and thyroglobulin antibodies. These tests are important for anyone with abnormal thyroid levels, a family history of thyroid disease, or symptoms of thyroid dysfunction.
Measures TPO antibodies + Thyroglobulin antibodies to diagnose autoimmune thyroid disease (Hashimoto's, Graves'). Confirms etiology when TSH is abnormal.
Anyone with abnormal TSH or Free T4, family history of autoimmune thyroid disease, unexplained miscarriage, postpartum thyroiditis suspicion, or other autoimmune conditions.

Two: TPO (Thyroid Peroxidase) antibodies and Thyroglobulin antibodies. TPO is the more sensitive marker for Hashimoto's; Thyroglobulin adds confirmation. For Graves' disease specifically, TSI (Thyroid-Stimulating Immunoglobulin) is a different test.
TPO antibodies above 35 IU/mL or thyroglobulin antibodies above 4 IU/mL are typically considered positive. Strongly elevated TPO (>500) with abnormal TSH essentially confirms Hashimoto's.
Yes — about 10% of healthy adults have detectable TPO antibodies without dysfunction. But positive antibodies raise the lifetime risk of developing overt hypothyroidism by 2-4x, so they warrant annual TSH monitoring.
On TestWell, the Thyroid Antibodies test (TPO + Thyroglobulin Ab) is $51.99. Quest Direct lists the bundle at $75, walk-in hospital labs typically bill $180-220 without insurance.
TPO antibodies: CPT 86376. Thyroglobulin antibodies: CPT 86800. Both billed together on a single requisition.
