Thyroid-Stimulating Immunoglobulins
(TSI)

Autoimmune diseases cause the body to attack itself, which leads to inflammation and results in damage to muscles, tissues, and organs. The inflammation produces antibodies in the blood that can be measured and the levels used to diagnose specific autoimmune diseases. TSI is a blood test that detects antibodies against thyroid cells bound with TSH; this results in either increased production or decreased production of thyroid hormone by the thyroid gland. High TSI blood levels are seen in people with Grave's disease, Hashimoto's thyroiditis, or an over-active thyroid gland. TSI levels are used to monitor how well you are responding to treatment, and diagnose recurrence of thyroid disease.
