What Are Thyroid Peroxidase Antibodies?

Thyroid peroxidase antibodies (TPOab) are autoantibodies that are part of the body’s immune system and attack the cells in the thyroid gland. They can interfere with the production of thyroid hormones and also be used to diagnose thyroid disorders.

How Are TPOab Tested?

TPOab is measured with a blood test. It looks for the presence of TPOab proteins, which are antibodies that can cause inflammation in the thyroid. The test is usually ordered by a doctor if they suspect that a person may have a thyroid disorder or autoimmune disease.

What Does a Positive TPOab Test Result Mean?

A positive TPOab test result means that the body’s immune system is attacking the thyroid. This can lead to thyroid disorders such as Hashimoto’s thyroiditis and Graves’ disease.

What Are the Symptoms of Thyroid Disorders?

The symptoms of thyroid disorders vary depending on the type of disorder and how far along it is. Common signs and symptoms include:

  • Fatigue
  • Weight gain
  • Dry skin
  • Depression
  • Nervousness
  • Muscle weakness

How Is Thyroid Disorder Diagnosed?

In addition to a TPOab test, thyroid disorders can be diagnosed with a physical exam, blood tests, and an ultrasound. The doctor may also order a thyroid-stimulating hormone (TSH) test to measure the amount of TSH in the blood. High levels of TSH can indicate that the thyroid is underactive (hypothyroidism). Low levels of TSH can indicate that the thyroid is overactive (hyperthyroidism).

What Is the Treatment for Thyroid Disorders?

The treatment for thyroid disorders depends on the type of disorder. Hypothyroidism is typically treated with a daily dose of synthetic thyroid hormone, while hyperthyroidism is treated with medications, radioactive iodine, or surgery.

Conclusion

TPOab is a test used to measure autoantibodies in the blood that can attack the thyroid. A positive TPOab test result may indicate a thyroid disorder such as Hashimoto’s thyroiditis or Graves’ disease. Diagnosis of thyroid disorders also involves a physical exam, blood tests, and an ultrasound. Treatment for thyroid disorders depends on the type and typically involves taking a daily dose of synthetic thyroid hormone, medications, and/or surgeries.
