Mindray-BC5300检测末梢全血时检测时间对血液分析结果的影响

Effect of tip blood testing time on blood analysis results by BC5300

目的：探讨Mindray-BC5300检测末梢全血时检测时间对血液分析结果的影响。方法：用BC5300血液分析仪对30例末梢全血标本分别于采血后0、5、10、30min连续检测，观察血液分析结果中WBC，RBC，HB，HCT，PLT，Neu％，Lym％等主要指标的变化。并将其中10例同时采集静脉血作为参考比较。结果：采血后0min分别与5min，10min，30min相比，WBC、PLT、Neu％，Lyre％差异有统计学意义（P〈0．05），而其他参数间差异无统计学意义（P〉0．05）；采血后5min和10min相比，所有参数间差异无统计学意义（P〉0．05）；采血后5min和30min相比与采血后10min和30min相比，PLT差异有统计学意义（P〈0．05），而其他参数间差异无统计学意义（P〉0．05）。10例静脉血结果与5min，10min末梢全血各参数间差异无统计学意义（P〉0．05）。结论：BC5300检测末梢全血时，采集后立即检测会对某些指标有明显影响，应在放置后5～10min内进行检测。

Objective：To investigate the effect of testing time on the result of tip blood samples by Mindray BC5300. Method：The 30 tip blood samples were detected at 0,5,10,30 rain after blood drawing by BC5300 and the results of WBC,RBC, HB, HCT,PLT, Neu% and Lym% were analyzed. Meanwhile, venous blood samples of 10 patients were detected as reference. Result.. Only WBC, PLT, Neu% and Lym% had significantly changed at 5,10 and 30 rain from 0 min（P〈0.05） ; while all the parameters had no significant changes from 5 to 10 min（P〉 0.05）. Only PLT had significantly changed at 30 min compared with 5 and 10 min. Ten results of venous blood samples had no significant changes from 5 and 10 min（P〉0.05）. Conclusion：The tip blood samples should be detected at 5 to 10 min after blood drawing by BC5300.
