Test Overview
Thyroid Antibodies Panel (Anti TPO, Anti TG) Test
The Thyroid Antibodies Panel is vital for evaluating autoimmune thyroid disorders. The tests within the panel reveal the immune system's reaction to the thyroid gland, pointing to conditions like Hashimoto's thyroiditis or Graves' disease. Anti-TPO antibodies focus on the thyroid peroxidase enzyme, vital for making thyroid hormones. Increased Anti-TPO levels indicate an autoimmune attack on the thyroid gland, often linked to hypothyroidism. On the flip side, Anti-TG antibodies target thyroglobulin, a protein in thyroid hormone production. Elevated Anti-TG levels are associated with both Hashimoto's and Graves' diseases.

Frequently asked questions
A positive result indicates the presence of autoimmune thyroid antibodies, suggesting an underlying autoimmune thyroid disorder that requires further evaluation and management.
While it is commonly used for individuals with symptoms, the test may also be ordered as part of routine monitoring for those already diagnosed with autoimmune thyroid disorders.
The panel usually includes tests for thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb), which are key markers for autoimmune thyroid conditions.
The test is commonly performed through a blood sample, collected through a simple blood draw.
While the test is indicative of autoimmune thyroid disorders, additional clinical information and tests are often needed for a definitive diagnosis.
No, the Thyroid Antibodies Panel specifically checks for antibodies associated with autoimmune thyroid diseases, providing information beyond what is assessed in routine thyroid function tests.
Individuals with unexplained thyroid dysfunction symptoms or a family history of autoimmune thyroid disorders are often recommended to undergo this test.
The frequency of testing for thyroid antibodies depends on the individual's health status and the guidance of their healthcare provider, but regular monitoring is typically advised for those with autoimmune thyroid disorders.
While lifestyle changes may impact overall thyroid health, the presence of thyroid antibodies is primarily indicative of autoimmune factors rather than lifestyle influences.
The frequency of testing varies based on the individual's condition and treatment plan; however, regular monitoring is typically recommended.
