What is TPO Antibodies?
TPO antibodies (thyroperoxidase antibodies) are antibodies that are formed against the enzyme thyroperoxidase (TPO) in the thyroid gland. TPO is an enzyme responsible for converting iodine into the hormones thyroxine (T4) and triiodothyronine (T3).
Why analyze TPO antibodies?
TPO antibodies are analyzed to identify if there is any autoimmune disease in the thyroid gland, such as Hashimoto's thyroiditis. This disease causes damage to thyroid cells and reduced production of hormones.
What can a high TPO antibodies value mean?
A high value of TPO antibodies can mean that there is an active autoimmune disease in the thyroid gland, such as Hashimoto's thyroiditis. It can also mean an increased risk of developing this disease in the future.
What can a low TPO antibodies value mean?
A low value of TPO antibodies usually means that there is no active autoimmune disease in the thyroid gland. It can also mean that the disease is in an early phase or does not affect the thyroid gland at the moment. However, it is important to note that this is general information and it is important to consult a doctor for a complete evaluation and diagnosis of thyroid problems.
