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

About TSI Test - Thyroid Stimulating Blood Test in Severn
Thyroid-stimulating immunoglobulin is an autoantibody that binds to the thyroid-stimulating hormone receptor and activates it.
In a healthy thyroid, thyroid-stimulating hormone from the pituitary gland regulates hormone production. In some autoimmune thyroid conditions, TSI takes on a similar stimulating role and causes persistent overactivity.
Because TSI acts at the receptor level, its presence can be distinguished from other thyroid antibodies that do not stimulate the gland. The test result is interpreted alongside thyroid hormone levels and the clinical picture.
TSI testing is most often used when an autoimmune cause of thyroid overactivity is suspected, when the cause of abnormal thyroid function is unclear, or when monitoring a known autoimmune thyroid disorder.
