Order TSI Test - Thyroid Stimulating Blood TestThe TSI test measures thyroid-stimulating immunoglobulin in the blood.

The test is used to evaluate the cause of hyperthyroidism and to help distinguish autoimmune thyroid disease from other conditions.
About TSI Test - Thyroid Stimulating Blood Test in Carlsbad
TSI testing provides a direct look at an antibody that can act on the thyroid gland.
Thyroid-stimulating immunoglobulin is an autoantibody that binds to the thyroid-stimulating hormone receptor. When it does, it can activate the receptor and prompt the thyroid to release more hormone than the body needs.
Because TSI can cross the placenta, the test is also used in pregnancy when a person has a history of autoimmune thyroid disease. In that setting, it helps assess the chance of thyroid-related effects in the newborn.
Results are interpreted alongside thyroid function tests and clinical findings. A positive result supports an autoimmune cause, while a negative result does not rule out every form of thyroid disease.
