The TSI (Thyroid-Stimulating Immunoglobulin) test is a blood test that measures antibodies that can overstimulate the thyroid gland. It is most often ordered to help diagnose Graves' disease, an autoimmune condition that causes hyperthyroidism, and to monitor treatment response.
What it measures
- TSI level — The amount of thyroid-stimulating immunoglobulin in the blood; higher levels suggest Graves' disease.
- TSI index — A calculated ratio that compares your TSI level to a reference standard, helping interpret results.
- TSI percentage — Sometimes reported as a percentage of a normal reference range, indicating relative antibody activity.
- Thyroid-stimulating antibody (TSAb) — A related antibody that may be measured alongside TSI to assess thyroid stimulation.
Who it is for
A doctor typically orders a TSI test when you have symptoms of hyperthyroidism, such as unexplained weight loss, rapid heartbeat, or tremors, or when other thyroid tests suggest Graves' disease.
Preparation
No fasting or special preparation is needed for a TSI test. You can eat and drink normally before your blood draw.
Results and what they mean
