Order TPO Test (Thyroid Peroxidase Antibody)The TPO test measures thyroid peroxidase antibodies, which are proteins the immune system can produce against an enzyme in the thyroid gland. Because these antibodies are a marker of autoimmune thyroid activity, the test is often used to clarify what is driving an abnormal thyroid picture.
About TPO Test (Thyroid Peroxidase Antibody) in Wheaton
Thyroid peroxidase is an enzyme the thyroid uses to build thyroid hormones. When the immune system mistakenly targets it, the resulting antibodies can be detected in blood.
Thyroid peroxidase, or TPO, sits at the heart of thyroid hormone production. It helps attach iodine to a protein called thyroglobulin, a step that eventually yields the hormones that regulate metabolism, energy use, and temperature. In some people, the immune system identifies TPO as a threat and creates antibodies against it.
Those antibodies do not act like a switch that simply turns the thyroid off or on. Their presence signals that an autoimmune process is affecting the gland, and that process can be associated with an underactive thyroid, an inflamed thyroid, or, in some cases, a thyroid that still functions normally.
Clinicians order a TPO test when bloodwork or symptoms suggest an autoimmune component, or when the cause of a thyroid problem is unclear. Results are interpreted alongside thyroid hormone levels and other findings, not in isolation.
