摘要
目的探讨静脉血样本在室温下放置时间对血常规测定有无影响。方法50例体检健康者静脉血经乙二胺四乙酸三钾抗凝，置室温（18-25℃）分别于即刻、30min、2h、6h采用SysmexK-21全自动血细胞分析仪进行血常规测定。结果2h内测定血常规各项参数与即刻结果比较差异无统计学意义（P〉0．05）。静脉血放置6h后，中间细胞百分比、血小板计数、血小板平均体积、血小板体积分布宽度与即刻比较差异有统计学意义（P〈0．05）；而其他参数差异无统计学意义（P〉0．05）。结论血常规测定应在2h内完成。
Objective To discuss effect of venous blood sample storage time on blood routine test under room temperature. Methods Put 50 healthy persons＇ EDTA K 3 anti-coagnlated venous blood samples under room temperature（18-25℃ ） ,and do blood routine tests instantly, at 30 minutes,2 hours and 6 hours respectively by using Sysmex K-21 Automatic Blood Cell Analyzer. Results There are of no significant differences in all blood cell parameters within 2 hours compared with the one at instant （P〉0.05）. There exists significant difference in MXD,PLT,MPV and PDW after 6 hours compared with the one at instant （P〈0.05）. Comparing rest parameters at 6 hours and instant,there are of no significant differences either （P〉0.05）. Conclusion Blood routine test should be done within 2 hours.
