Order TSI Test - Thyroid Stimulating Blood TestThe TSI test measures thyroid-stimulating immunoglobulin, an antibody that can mimic the action of thyroid-stimulating hormone. Because this antibody binds to the thyroid gland's receptor and prompts it to produce more thyroid hormone, its presence offers a specific clue about how the thyroid is being driven. The test is most often used when a clinician needs to distinguish autoimmune thyroid overactivity from other causes of an overactive thyroid.
About TSI Test - Thyroid Stimulating Blood Test in Berkeley
Thyroid-stimulating immunoglobulin is an autoantibody directed at the thyroid-stimulating hormone receptor.
In a healthy system, thyroid-stimulating hormone from the pituitary gland tells the thyroid how much hormone to make. Thyroid-stimulating immunoglobulin bypasses that regulation by attaching to the same receptor and switching it on, which can lead to sustained overproduction of thyroid hormone.
The TSI test detects and, depending on the laboratory method, quantifies this antibody in the blood. Results are interpreted alongside thyroid hormone levels such as TSH, free T4, and free T3, because the antibody itself does not act alone; it is one part of a larger thyroid picture.
TSI testing is commonly ordered when the cause of an overactive thyroid is uncertain, when a clinician is evaluating an autoimmune thyroid condition, or during monitoring of a known thyroid-stimulating immunoglobulin-related disorder. Turnaround for results is typically one to three business days, and preparation follows the lab's instructions.
