The CS5100 analyzer (Sysmex) was validated for the determination of routine coagulation parameters. This fully automated coagulation analyzer uses multiple wavelength technology to perform coagulation (e.g., activated partial thromboplastin time - APTT, prothrombin time - PT, fibrinogen - FBG), chromogenic (e.g., antithrombin - AT) and immunological (e.g., D-dimers - DDi) assays.
A comparison with the currently used STA-R Evolution (Stago) was performed. Validation and verification of reference values of the CS5100 was performed in accordance to CLSI guidelines (H57-A, H47-A2, and C28-A3).
As a different detection system and reagents were used, significant differences were observed (e.g. APTT). The within-day and between-day imprecision, accuracy and total error were all acceptable. The reference values defined by the manufacturer could be used except for APTT. In our settings, the therapeutic anti-Xa range of 0.3-0.7 IU/mL corresponded to an APTT range of 60-100 s (Dade actin FS reagent). The APTT reagent showed factor sensitivities between 46 and 72% for FVIII, IX, XI and XII while the PT reagent showed sensitivities between 34 and 52% for FII, FV, FXII, and FX.
In conclusion, the CS5100 instrument is suitable for the determination of the APTT, PT, FBG, DDi and AT in routine analysis.
CS5100分析仪(希森美康公司)已通过常规凝血参数测定的验证。这款全自动凝血分析仪采用多波长技术进行凝血检测(如活化部分凝血活酶时间 - APTT、凝血酶原时间 - PT、纤维蛋白原 - FBG)、发色底物法检测(如抗凝血酶 - AT)和免疫检测(如D - 二聚体 - DDi)。
与当前使用的STA - R Evolution(思塔高公司)进行了比较。按照CLSI指南(H57 - A、H47 - A2和C28 - A3)对CS5100的参考值进行了验证和核查。
由于使用了不同的检测系统和试剂,观察到显著差异(如APTT)。日内和日间不精密度、准确性和总误差均可接受。除APTT外,制造商定义的参考值均可使用。在我们的实验条件下,治疗性抗Xa范围为0.3 - 0.7 IU/mL对应APTT范围为60 - 100秒(达德肌动蛋白FS试剂)。APTT试剂对FVIII、IX、XI和XII的因子敏感性在46%至72%之间,而PT试剂对FII、FV、FXII和FX的敏感性在34%至52%之间。
总之,CS5100仪器适用于常规分析中APTT、PT、FBG、DDi和AT的测定。
