Point-of-care (POC) testing in the field of hemostasis is rapidly expanding in many countries. This includes use of global tests of hemostasis in operating theaters and especially use of POC monitors for determination of the international normalized ratio (INR) for monitoring oral anticoagulant therapy. Issues related to internal quality control and external quality assessment for these devices are reviewed. Data from external quality assessment exercises involving users of several different POC-INR devices is described, and use of split samples where a patient sample is analyzed by both a POC device and by a conventional laboratory method is described.
在许多国家，止血领域的即时检验（POC）正在迅速发展。这包括在手术室中使用止血的整体检测，尤其是使用即时检验监测仪来测定国际标准化比值（INR）以监测口服抗凝治疗。本文综述了这些设备的内部质量控制和外部质量评估相关问题。描述了来自涉及几种不同即时检验INR设备用户的外部质量评估活动的数据，还描述了使用分割样本的情况，即患者样本同时通过即时检验设备和传统实验室方法进行分析。
