Order TSI Test - Thyroid Stimulating Blood TestThe TSI test measures thyroid-stimulating immunoglobulin in the blood. This antibody can mimic thyroid-stimulating hormone and drive the thyroid to overproduce its hormones. Clinicians order TSI testing when they need a precise marker of autoimmune thyroid activity, particularly in the evaluation of Graves' disease.
About TSI Test - Thyroid Stimulating Blood Test in Dublin
Thyroid-stimulating immunoglobulin is an autoantibody that binds to the thyroid-stimulating hormone receptor.
The thyroid-stimulating hormone receptor sits on thyroid cells and normally responds to thyroid-stimulating hormone, or TSH. In some people, the immune system produces an antibody that binds this same receptor and activates it, prompting the gland to release more thyroid hormone than the body needs.
TSI testing quantifies that antibody activity in a blood sample. Because the antibody acts directly on the receptor, its presence helps distinguish autoimmune-driven hyperthyroidism from other causes of an overactive thyroid. It can also be useful when thyroid function tests give an ambiguous picture.
The test requires a standard blood draw, and results are typically reported within one to three business days. Preparation follows the laboratory's instructions. Results should be interpreted by a clinician alongside other thyroid tests and the patient's clinical history.
