New assay range including automated TSI
A range of new assays has been released by Siemens for use on the ADVIA Centaur and IMMULITE XPi 2000 systems. The range includes anti-CCP used as an aid in the evaluation of Rheumatoid Arthritis (RA) and the first automated quantitative thyroid stimulating immunoglobulin (TSI) assay used in the diagnosis of Graves’ disease. The ADVIA Centaur anti-CCP assay is for use in the semi-quantitative determination of the IgG class of autoantibodies specific to cyclic citrullinated peptide (CCP) in human serum and plasma, aiding with the diagnosis of RA. The assay provides 96% specificity for an early accurate diagnosis of RA, ensuring improved patient care by allowing timely intervention and treatment. The Siemens IMMULITE 2000 XPi thyroid stimulating immunoglobulin (TSI) assay specifically detects thyroid stimulating antibodies, which are the hallmark of Graves’ disease, unlike the commonly used TRAb assay which detects both stimulating and blocking antibodies. 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, it ensures laboratories can provide a fast, easy and specific diagnosis. The addition of the new assays to the existing extensive range will help laboratory staff integrate testing into routine workflow, reducing the need for send-away testing. This enables laboratories to reduce operational costs and time, as well as becoming more productive and efficient.
