    This blood test is a combination test used to evaluate both, Thyroid Autoantibodies (TAA) and Thyroid Peroxidase Antibodies (TPO ab). Thyroid autoantibody (TAA) is a test that helps to determine if an autoimmune process is manifesting in the thyroid system. Autoantibodies to thyroglobulin (thyroid hormone) may lead to the destruction of the thyroid gland. Antibodies are more likely to appear after trauma or inflammation of the thyroid gland. Thyroid Peroxidase antibodies (TPO ab) is an important antibody test related to the thyroid gland because thyroid peroxidase is the enzyme responsible for the production of thyroid hormones. This enzyme plays a central role in the function of the thyroid gland. Thyroid peroxidase assists the chemical reaction that adds iodine to a protein called thyroglobulin, a critical step in generating thyroid hormones. Thyroid hormones play an important role in regulating growth, brain development, and the rate of chemical reactions in the body (metabolism).

    Test Preparation For Optimal Results:
    If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
