- The presence of TPO antibodies in your blood suggests that the cause of thyroid disease is an autoimmune disorder, such as Hashimoto's disease or Graves' disease.In autoimmune disorders, your immune system makes antibodies that mistakenly attack normal tissue.ntibodies that attack the thyroid gland cause inflammation and impaired function of the thyroid. Your doctor may also order a TPO antibody test if you are pregnant and have an autoimmune disease, especially one that involves the thyroid, such as Hashimoto's disease or Graves' disease.

Top 30 Doctor insights on: Anti Thyroid Peroxidase Normal Range 2 doctors agreed: Thyroid peroxidase: An elevated anti-TPO antibodies could indicate Hashimoto's thyroiditis. However, it is not clear that yours are actually elevated. If the TSH is normal, it is unlikely that this is affecting you; maybe these are perimenopausal sx.

Hypothyroidism Diagnosis A third hypothyroid test is for anti-thyroid microsomal antibodies—anti-thyroid peroxidase (anti-TPO). These antibodies, which are produced by the immune system, may attack thyroid cells. If a blood test determines their presence, it shows that there has been thyroid damage which could potentially lead to hypothyroidism. This autoimmune damage characterizes Hashimoto's thyroiditis. Most primary care physicians do not test for anti-thyroid microsomal antibodies, so your doctor may refer you to a specialist for this particular test.

- A thyroglobulin antibody (TgAb) test is typically ordered along with the thyroglobulin test. Thyroglobulin antibodies (also called thyroglobulin autoantibodies) are proteins produced by the body's immune system that attack thyroglobulin. thyroglobulin test may be ordered prior to the surgical removal of the thyroid gland for cancer. It may also be ordered after the completion of treatment to help determine whether any normal and/or cancerous thyroid tissue may have been left behind.

Useful For See Thyroid Function Ordering Algorithm in Special Instructions. Thyroperoxidase (TPO) is an enzyme involved in thyroid hormone synthesis, catalyzing the oxidation of iodide on tyrosine residues in thyroglobulin for the synthesis of triiodothyronine and thyroxine (tetraiodothyronine).

- Hashimoto thyroiditis is also known as goitrous chronic thyroiditis. Almost all patients with this disease have positive test results for the thyroid peroxidase antibody (anti-TPO), an autoantibody against thyroid peroxidase enzyme.Of these patients, 50-70% also have positive results for antithyroglobulin antibodies.athophysiology. The defect that predisposes an individual to develop autoimmune thyroid disease is still unknown. Proposed mechanisms include a tissue-specific defect in suppressor T-cell activity, a genetically programmed presentation of a thyroid-specific antigen, and an idiotype/anti-idiotype reaction.

Thyroid Antibodies Testing for thyroid antibodies, such as thyroid peroxidase antibody (TPO), is primarily ordered to help diagnose an autoimmune thyroid disease and to distinguish it from other forms of thyroid dysfunction. person who is receiving treatment for thyroid cancer may be monitored with a thyroglobulin test. In this case, the thyroglobulin antibody test is used to determine if the antibody is present in the person's blood and likely to interfere with the test to measure the thyroglobulin level.

Autoantibodies to thyroid peroxidase (TPOAb) are produced within the body.The presence of TPOAb in the blood reflects a prior attack on the thyroid tissue by the body's immune system.PO is found in thyroid follicle cells where it converts the thyroid hormone T4 to T3. The thyroid gland is located in the lower part of the neck, below the Adam's apple, wrapped around the trachea (windpipe).

Which Thyroid Antibody Assays Should be Checked in Patients with Thyroid Disease? ANTI-THYROGLOBULIN and ANTI-THYROID PEROXIDASE ANTIBODIES. Thyroglobulin (Tg) is a large glycoprotein that is synthesized by follicular cells in the thyroid gland and secreted into the lumen of the thyroid follicle. Thyroid peroxidase (TPO) is a key enzyme in the production of thyroid hormone.or example, in Graves’ disease activation of the thyroid stimulating hormone receptor causes increased production of thyroid hormone leading to hyperthyroidism 1, and in Hashimoto’s thyroiditis, anti-anti-thyroid peroxidase antibodies block organification of iodine and may lead to reduced T-4/T-3 levels.

Thyroid Antibodies Significantly increased concentrations most frequently indicate thyroid autoimmune diseases such as Hashimoto thyroiditis and Graves disease. In general, the presence of thyroid antibodies suggests the presence of an autoimmune thyroid disorder and the higher the level, the more likely that is.esting may be performed as a follow-up when other thyroid test results such as total or free T3, free T4, and/or TSH indicate thyroid dysfunction. One or more thyroid antibody tests may also be ordered to determine if a person with an autoimmune condition is at risk of developing thyroid dysfunction.

Thyroid Antibody Tests For example, positive anti-thyroid peroxidase and/or anti-thyroglobulin antibodies in a patient with hypothyroidism make a diagnosis of Hashimoto’s thyroiditis. If the thyroid antibodies are positive in a hyperthyroid patient, the most likely diagnosis is autoimmune thyroid disease.hether the antibodies cause the disease or whether the disease causes the antibodies is not known; however, the finding of a high level of thyroid antibodies is strong evidence of this disease. Occasionally, low levels of thyroid antibodies are found with other types of thyroid disease.

Thyroid Function Tests If the initial thyroid test results show signs of thyroid dysfunction and if there is a suspicion of an autoimmune thyroid disease, one or more thyroid antibody tests may be ordered. The main thyroid antibodies are thyroid peroxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb), and thyroid stimulating hormone receptor antibodies (TSHR Ab formerly known as TRAb).

Thyroid Antibodies The Test Sample. What is being tested? Thyroid autoantibodies are antibodies that develop when a person's immune system mistakenly targets components of the thyroid gland or thyroid proteins, leading to chronic inflammation of the thyroid (thyroiditis), tissue damage, and/or disruption of thyroid function.
