We report aggregate turnaround times (TATs) from phlebotomy to result reporting of emergency department patients' hemoglobin and potassium results for 722 subscribers to the College of American Pathologists Q-Probes program. Approximately 40,000 specimens were obtained for each analyte. Median interinstitutional TAT time of 25 minutes for hemoglobin and 36 minutes for potassium varied little by shift, weekdays, or weekends. The type of personnel collecting the specimen and the method of specimen transport were the most important factors affecting TATs. Specimen transit times accounted for approximately one third of the total TATs, but when couriers transported hemoglobin specimens, the median transit time was equivalent to the median intralaboratory test TAT. The influence of various measures used to improve test transit and TATs is presented.
我们报告了美国病理学家学会Q-Probes项目722名订阅者的急诊科患者血红蛋白和钾检测结果从静脉穿刺到结果报告的总周转时间（TAT）。每种分析物大约采集了40000份标本。血红蛋白的机构间TAT中位数为25分钟，钾为36分钟，在不同班次、工作日或周末变化不大。采集标本的人员类型和标本运输方式是影响TAT的最重要因素。标本运输时间约占总TAT的三分之一，但当快递员运输血红蛋白标本时，中位数运输时间与实验室内部检测TAT中位数相当。本文介绍了用于改善检测运输和TAT的各种措施的影响。
