Thyroidal peroxidase antibodies (TPOAb)
Thyroidal peroxidase antibodies (TPOAb) are directed against microsomes (small structures within a thyroid cell) in the thyroid gland. With the help of the thyroid enzyme thyroid peroxidase (TPO), the effective thyroid hormones thyroxine (T4) and triiodothyronine (T3) are produced. Highly elevated TPO-Ak levels in the serum occur mainly in Hashimoto’s thyroiditis. In Hashimoto’s thyroiditis, after an initial hyperfunction, the thyroid can become permanently hypothyroid because thyroid tissue is destroyed in the course of the disease.

Free T3
Triiodothyronine (T3) is one of two thyroid hormones. It is formed from thyroxine (T4) and stimulates different metabolic processes. A small part of T3 occurs freely in the blood serum.
