Thyroid Peroxidase Antibodies
Thyroid
Thyroid Peroxidase Antibodies (Anti-TPO) are produced by the immune system as a defence mechanism to protect the thyroid against foreign invaders. Autoimmune condition will increase the amount of anti-TPO in the body, attacking healthy thyroid cells. Anti-TPO tests are used to diagnose thyroid disorders and are an indicator for autoimmune conditions. Note: this is only tested in the Full Thyroid Profile blood test.
