Order TSI Test - Thyroid Stimulating Blood TestThe TSI test measures thyroid stimulating immunoglobulin, an antibody that can mimic thyroid stimulating hormone and drive the thyroid gland to overproduce hormone. Because it acts at the receptor level, the test offers a direct look at an autoimmune process rather than an indirect inference from hormone levels alone.
About TSI Test - Thyroid Stimulating Blood Test in Wichita Falls
Thyroid stimulating immunoglobulin is an autoantibody directed against the thyroid stimulating hormone receptor.
In Graves' disease, this antibody binds the receptor and triggers sustained thyroid hormone production and gland growth. Measuring TSI helps distinguish that autoimmune mechanism from other causes of an overactive thyroid.
The test is a blood draw, and results are typically reported as a percentage of activity or an index relative to a reference standard. Interpretation depends on the assay method used by the laboratory, so values should be read against the range provided with the report.
TSI is often ordered alongside thyroid stimulating hormone, free thyroxine, and free triiodothyronine to build a fuller picture of thyroid status. It can also be used to monitor antibody activity over time in people with known autoimmune thyroid disease.
