Point-of-care (POC) tests provide analytical information that can be used to make decisions at patients' bedside, as opposed to laboratory tests that must be run at a central laboratory. POC testing is a widely used tool to enable immediate determination of glucose levels in hospitalized patients and facilitate rapid treatment decisions in response to fluctuations in glycemia. Accurate POC glucose testing requires attention to various factors before, during, and after performance of tests. These include 1) proper preparation of test sites to avoid preanalytical errors, 2) proper identification of tested patients whose physiological status permits sampled capillary specimens to correlate with central venous blood glucose levels to avoid analytical errors, and 3) proper documentation of the fidelity of meter results with the medical record to avoid postanalytical errors.
即时检验（POC）可提供分析信息，用于在患者床边做出决策，这与必须在中心实验室进行的实验室检测不同。POC检测是一种广泛使用的工具，可即时测定住院患者的血糖水平，并有助于根据血糖波动迅速做出治疗决策。准确的POC血糖检测在检测前、检测中和检测后都需要注意各种因素。这些因素包括：1）正确准备检测部位以避免分析前误差；2）正确识别受检患者，其生理状态允许采集的毛细血管样本与中心静脉血糖水平相关，以避免分析误差；3）将血糖仪结果的准确性与病历进行正确记录，以避免分析后误差。
