Order TSI Test - Thyroid Stimulating Blood TestThe TSI test measures thyroid-stimulating immunoglobulin in the blood. This antibody mimics thyroid-stimulating hormone and can drive the thyroid to produce excess hormone. Clinicians use the test to investigate the cause of hyperthyroidism and to distinguish Graves' disease from other thyroid conditions.
About TSI Test - Thyroid Stimulating Blood Test in Cedar City
Thyroid-stimulating immunoglobulin is an autoantibody that binds to the thyroid-stimulating hormone receptor.
In a healthy thyroid, thyroid-stimulating hormone from the pituitary gland regulates hormone production. In Graves' disease, TSI binds to the same receptor and stimulates the gland independently, leading to elevated thyroid hormone levels and suppressed TSH.
Because TSI is specific to this autoimmune process, its presence helps confirm Graves' disease when other thyroid tests and clinical findings are consistent. It can also be useful in monitoring treatment response and in assessing the risk of thyroid dysfunction in pregnancy.
Results are interpreted alongside TSH, free T4, free T3, and sometimes other thyroid antibodies. A positive result supports an autoimmune cause, while a negative result does not rule out thyroid disease and should be evaluated in the full clinical context.
