About TSI Test - Thyroid Stimulating Blood Test in Florence Graham
Thyroid-stimulating immunoglobulin is an autoantibody directed against the thyroid-stimulating hormone receptor.
In a healthy system, thyroid-stimulating hormone from the pituitary gland regulates thyroid hormone production. Thyroid-stimulating immunoglobulin binds to the same receptor and activates it, often without the usual feedback control.
The TSI test is typically ordered when a clinician suspects an autoimmune cause of hyperthyroidism, particularly Graves' disease. It can also be used to monitor the course of that condition or to assess the risk of thyroid dysfunction in a newborn whose mother has a history of the disorder.
Results are interpreted alongside thyroid function tests such as TSH, free T4, and free T3, as well as the patient's symptoms and clinical history. A positive result supports an autoimmune mechanism but is not a stand-alone diagnosis.
