Tests Included:

Anti-thyroglobulin Antibody (TAA): This test helps to detect possible thyroid problems. Thyroglobulin is a protein that is normally confined to the thyroid gland. It is the source of the thyroxine and triiodothyronine hormones in the body. The presence of auto-antibodies to thyroglobulin can lead to the destruction of the thyroid gland. Such antibodies are more likely to appear after trauma to, or inflammation of, the thyroid gland.

Thyroid Peroxidase (TPO) Antibodies: The TPO gene provides instructions for making an enzyme called thyroid peroxidase. 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).
