Thyroid Peroxidase Antibody Blood Test

  • Item # LC006676

Measures thyroid peroxidase antibody to assess thyroid function

If you or your health practitioner is concerned that you may have developed a low thyroid condition, this test will detect antibodies to thyroid peroxidase (TPO) levels, which are markers of autoimmune thyroid disease.

This test measures thyroid peroxidase antibody (TPO) and is often used in conjunction with the antithyroglobulin antibody (ATA). Doctors often use these tests to help them assess thyroid function, follow treatment for thyroid disease, and differentiate between autoimmune conditions of the thyroid.

Antibodies to thyroid peroxidase can result in symptoms of low thyroid such as fatigue, weight gain, dry skin, and constipation. Conditions such as Hashimoto’s thyroiditis, lupus, rheumatoid arthritis, and pernicious anemia often have these antibodies present.


Fasting is not required for this test. Take all medications as prescribed.


For a more extensive evaluation of thyroid function, Life Extension® offers a Comprehensive Thyroid Panel.
