A questionnaire on the preanalytical problems including blood sampling, sample care and transportation was sent to members of the Fukushima Association of Medical Technologists in 118 hospitals. Answers were received from 88 institutions. In more than 90% of the hospitals, blood sampling and transportation of specimens were carried out by nurses. Bleeding from the hospitalized patients was routinely performed early in the morning starting as early as at 5 AM in 40%, at 6 AM in 42% and at 7 AM in 7% of the hospitals. After bleeding, samples for blood cell counting and coagulation studies were transported immediately to the laboratories in 27% and 42% of the institutions respectively. However, blood samples for biochemical analyses and urine samples were stored at room temperature, and the average time until the start of analysis was suggested to be 3 to 4 hours. In the course of this survey and discussion, the importance of preanalytical quality control was better recognized by laboratory staff. Better communication among laboratory staff, nurse, and doctor will improve the preanalytical quality control.
一份关于包括血液采样、样本处理及运输等分析前问题的调查问卷被发送给了福岛医学技术人员协会中118家医院的成员。共收到了88家机构的回复。在超过90%的医院中，血液采样和样本运输由护士负责。住院患者的采血通常在清晨进行，40%的医院最早从凌晨5点开始，42%的医院在早上6点开始，7%的医院在早上7点开始。采血后，分别有27%和42%的机构将用于血细胞计数和凝血研究的样本立即送往实验室。然而，用于生化分析的血液样本和尿液样本被保存在室温下，分析开始前的平均时间被认为是3至4小时。在本次调查和讨论过程中，实验室工作人员对分析前质量控制的重要性有了更好的认识。实验室工作人员、护士和医生之间更好的沟通将改善分析前质量控制。
