即时检验(point-of-care test, POCT)是一种在不同临床环境下提供检测结果的快速手段，可排除标本运输等因素对结果的影响，但其同样具有潜在错误结果的风险。随着风险管理理论的提出，对POCT中的风险识别、控制和降低逐渐引起实验室人员的关注，迫切需要改善测定结果的准确性，降低患者伤害风险。

Point-of-care test (POCT), is a rapid method to provide test results in different clinical environments. It can exclude the influence of sample transportation and other factors on the results, but it also has the risk of potential erroneous results. With the development of risk management theory, more and more attention has been paid to risk identification, control and reduction in POCT. There is an urgent need to improve the accuracy of the results and reduce the risk of injury to patients
