GlossaryThyroid Peroxidase Antibodies

immune proteins attacking thyroid enzyme, linked to autoimmune disorders

Thyroid Peroxidase Antibodies (TPO Antibodies) are immune system proteins that mistakenly target and attack thyroid peroxidase, an enzyme crucial for the production of thyroid hormones. Elevated levels of TPO antibodies are often associated with autoimmune thyroid disorders, such as Hashimoto's thyroiditis and Graves' disease, and can lead to symptoms like hair loss, fatigue, and weight changes.
