First Automated and Quantitative TSI Thyroid Assay for Graves' Disease Launched

摘要

Siemens Healthcare Laboratory Diagnostics business area announced today the launch of the industry's first automated quantitative thyroid stimulating immunoglobulin (TSI) assay used in the differential diagnosis of Graves' disease, an autoimmune disorder which affects approximately 32 million people worldwide. The assay is available on the Siemens IMMULITE 2000 and IMMULITE 2000 XPi immunoassay systems. Unlike TRAb (TSH receptor antibody) assays which detect both stimulating and blocking antibodies, the Siemens TSI assay specifically detects only thyroid stimulating antibodies, which are the hallmark of Graves' disease. This makes the assay highly specific to aid in the disease's diagnosis. With a clinical sensitivity and specificity of 98.3% and 99.7% respectively, the new Siemens TSI assay offers laboratories a fast, easy, and specific diagnostic tool for the assessment of Graves' disease.
