What Are Thyroid Antibodies?

Thyroid antibodies are proteins that are produced when the body’s immune system mistakenly attacks its own thyroid gland, or when thyroid tissue is exposed to something the body views as a foreign material. These antibodies can be either pro-inflammatory or protective, depending on the specific antibody.

Types of Thyroid Antibodies

There are several types of thyroid antibodies, including:

  • Thyroglobulin Antibodies (TgAb): produce inflammation and can lead to Hashimoto’s thyroiditis, an autoimmune disorder.
  • Thyroid Peroxidase Antibodies (TPOAb): cause damage to the thyroid and can lead to hypothyroidism.
  • Thyroid Stimulating Hormone Receptors (TSHRab): promote an overactive thyroid, an autoimmune condition known as Graves’ disease.

Testing for Thyroid Antibodies

The most common test used to detect thyroid antibodies is the Thyroid Stimulating Hormone (TSH) test. This is usually done as part of a routine checkup, or if you have any symptoms that may be related to thyroid problems. If the TSH test shows your thyroid is functioning normally, your doctor may order additional tests to check for thyroid antibodies.

Treatment for Thyroid Antibodies

Most cases of thyroid antibodies do not require treatment, but depending on the results of the tests, your doctor may recommend lifestyle changes or medications to manage your condition.

Risks associated with Thyroid Antibodies

Certain types of thyroid antibodies can potentially increase your risk of developing thyroid-related conditions such as hypothyroidism or hyperthyroidism. It is important to be aware of your risk factors and talk to your doctor if you notice any changes in your health.
