Graves’ disease is characterized by the presence of TSI in the bloodstream which results in over-stimulation of the thyroid gland and low thyroid stimulating hormone (TSH) levels (hyperthyroidism).1 Eighty percent of Graves’ disease cases occur in women,1 and can be difficult to diagnose because symptoms vary greatly and often mimic other illnesses.2
Thyretain is an in vitro diagnostic use test that specifically detects auto-antibodies called thyroid stimulating immunoglobulins (TSI) in patient serum. Thyretain is the first commercial test that specifically detects TSI and is intended to be used as an aid in the differential diagnosis of Graves’ disease.
Thyretain is manufactured and distributed by Diagnostic Hybrids. For more information about Graves' Disease, please visit the National Graves' Disease Foundation.
