Autoimmune Thyroid Panel
Thyroid gland disorders are among the most common hormone conditions seen by doctors. The Autoimmune Thyroid Panel can tell whether or not you have an autoimmune hypothyroid condition, called Hashimoto Thyroiditis.
Hashimoto Thyroiditis is characterized by the body’s own immune proteins attacking the thyroid gland. This test detects levels of those antibodies to see if an autoimmune disease against the thyroid gland is present. This test panel also reports TSH, T4 and T3 to tell you whether your thyroid gland is producing enough thyroid hormone.

In the early stages of Hashimoto thyroiditis, thyroid hormone levels can be normal. Over time, however, as the immune system begins to destroy the thyroid gland and reduce the amount of thyroid hormone. This results in hypothyroid symptoms, such as fatigue, depression, decreased libido and weight gain.
In addition to testing the thyroid hormones to determine thyroid function, doctors test the anti-thyroglobuin (Anti-TG) and anti-thyroperoxidase (Anti-TP) antibodies to diagnose Hashimoto thyroiditis. Additionally, Anti-TG can be useful in the diagnosis and management of Graves' disease (hyperthyroid), certain types of goiter and to monitor patients who have had their thyroid gland removed because of thyroid cancer.
