Siemens Healthcare Diagnostics has added a new anti-CCP assay to its automated immunoassay menu for the Immulite 2000 and Immulite 2000 XPi immunoassay systems. The assay is a fully-automated test that offers laboratories a highly-specific immunoassay for the measurement of anti-CCP.
Anti-CCP is used as an aid in the diagnosis of rheumatoid arthritis (RA) through the semi-quantitative measurement of human IgG to cyclic citrullinated peptide (CCP) in serum and plasma. Timely RA diagnosis is critical in order to treat patients as early as possible, thereby delaying and/or preventing joint erosion. Anti-CCP antibodies precede clinical symptoms of RA by years and have proven to be a specific, predictive marker for early detection of the disease.
The Immulite 2000/2000 XPi anti-CCP assay is claimed to offer 'excellent' specificity, making it an ideal marker for both RA diagnosis and differentiation from other diseases. Its reagent stability is said to make it ideal for low volume testing with minimal reagent waste. In addition, with the ability to conduct the test in-house, laboratories are able to consolidate resources.
