In addition to screening for the thyroid hormones that play a key role in regulating metabolism, this advanced thyroid function test detects and measures the quantity of specific thyroid autoantibodies to determine whether autoimmune disease may be impacting thyroid function.
Thyroid peroxidase antibodies work against thyroid peroxidase, an enzyme that plays a part in the T4-to-T3 conversion and synthesis process. TPO antibodies can be evidence of tissue destruction, such as Hashimoto’s disease.
When your immune system attacks the thyroid it often targets thyroglobulin which causes it to produce antithyroglobulin antibodies. Thyroglobulin antibodies are positive in about 60% of Hashimoto’s patients and 30% of Graves patients.
