Anti-Thyroid Peroxidase Antibody Test Overview

Thyroid Peroxidase also known as TPO is an important enzyme used in the production of the thyroid hormone. The anti thyroid peroxidase antibody test is used to understand the underlying cause for thyroid disease in your body. As it is an antibody test, based on the results doctors can determine whether the cause of your thyroid disease is an autoimmune condition or not.

Autoimmune conditions cause the immune system to start attacking the body itself. In case of thyroid disease, the presence of an autoimmune condition indicates that it's affecting the thyroid gland. Based on the anti thyroid peroxidase antibody test reports, doctors can start treatment for the thyroid disease to help you manage the condition. Since autoimmune conditions are incurable, management techniques are what doctors rely on to manage the condition.

Changes to hair, skin, and nails become very dry.
