Testing for thyroid antibodies helps distinguish an autoimmune thyroid disease from other thyroid conditions. Thyroid autoantibodies develop when the immune system mistakenly targets components of the thyroid gland or thyroid proteins, leading to chronic thyroid inflammation and disruption.

Thyroid-stimulating hormone receptor antibodies are autoantibodies that attach to proteins in the thyroid and promote the production of thyroid hormones, leading to hyperthyroidism. Hyperthyroidism, or an overactive thyroid, occurs when the thyroid makes too much thyroxine (T4) and triiodothyronine (T3). An excess of thyroid hormones speeds up metabolism in the body. Hyperthyroidism symptoms include fatigue, unexplained weight loss, heart palpitations, sensitivity to heat and hair loss.

Our test helps investigate symptoms of hyperthyroidism when an autoimmune condition is suspected as TSH receptor-stimulating antibodies are often associated with Graves' disease. You can also use it to monitor the progress and effectiveness of anti-thyroid therapy.
