Low or suppressed Thyroid Stimulating Hormone (TSH), along with symptoms, is an early indicator of Hyperthyroidism.
At least 70% of Hyperthyroid patients suffer from an autoimmune disorder called Graves’ disease.
Thyroid Stimulating Immunoglobulins (TSIs) are antibodies that cause Graves’ disease.

Thyretain® TSI Reporter BioAssay is for the specific detection of thyroid-stimulating immunoglobulin (TSI) in the bloodstream, the antibodies directly linked to Graves’ disease.
