What this test is
The TSI test detects and measures thyroid stimulating immunoglobulin in the blood. This antibody can mimic thyroid stimulating hormone and cause the thyroid to produce excess hormone. It is most often used to help identify autoimmune-related thyroid overactivity.
What it measures
- Thyroid stimulating immunoglobulin (TSI) — Reflects the level of an antibody that can stimulate the thyroid gland
What the test involves
A blood sample is collected from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order a TSI test when thyroid blood tests suggest overactivity or when an autoimmune cause is suspected. It can also be used to monitor a known thyroid condition over time.
Preparation
Preparation is usually not required, but you should follow the specific instructions provided by the collection lab. This may include fasting or avoiding certain medications, depending on the lab's protocol.
How results are reported
Results are reported as a numeric value with a reference range that varies by laboratory. Your clinician will interpret the result in the context of your symptoms and other thyroid tests.

FAQ
Frequently asked questions
What is thyroid stimulating immunoglobulin?
Thyroid stimulating immunoglobulin is an antibody that binds to and activates the thyroid gland. It can cause the thyroid to produce too much hormone, leading to symptoms of overactive thyroid.
How is the TSI test different from other thyroid tests?
Other thyroid tests measure hormone levels or general antibodies, while the TSI test specifically measures an antibody that stimulates the thyroid. This can help distinguish autoimmune causes from other forms of thyroid overactivity.
Do I need to fast before a TSI test?
Fasting is not typically required for a TSI test. However, always follow the instructions given by the lab or your clinician, as they may have specific requirements.
What do TSI test results mean?
A high TSI level may suggest an autoimmune cause of thyroid overactivity. Results are interpreted alongside your symptoms and other thyroid tests, and reference ranges differ between laboratories.
