The Thyroid Stimulating Immunoglobulin test measures the level of thyroid-stimulating immunoglobulin (TSI) in your blood. High levels of TSI in the blood can indicate the presence of Graves’ disease, which is an autoimmune disorder that affects the thyroid gland. TSI is a form of immunoglobulin G (IgG) that can bind to thyrotropin (TSH) receptors on the thyroid gland. TSIs mimic the action of TSH, causing excess secretion of thyroxine and triiodothyronine.
