Automated and quantitative TSI thyroid assay for Graves’ disease

Siemens Healthcare Laboratory Diagnostics has launched 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. As the first automated quantitative TSI assay on the market, it eliminates the need for manual preparations and long incubation times. Not only does this automated assay streamline lab operations and enhance efficiency, it also delivers results to clinicians much more quickly enabling faster patient diagnosis and initiation of proper treatment. Graves’ disease is the most common form of hyperthyroidism, and is characterized by the presence of TSI, which are found in over 90 percent of patients. TSI mimic the activity of TSH, leading to an elevated production of thyroid hormone. Left untreated, Graves’ disease can lead to miscarriage, birth defects, thyroid eye disease, and can even be life-threatening. Women carry a 10 -20 fold risk of acquiring Graves’ disease compared to men.
