目的研究不同温度与时间条件下对血常规参数检测结果的影响。方法选择2014年7月—2015年7月在该院接受健康体检的人群的320份血液样本进行研究,根据保存温度的差异分成两组,各160份,A组置于室温保存,B组冷藏保存,对比两组血液样本不同时间段的MCH、WBC、Hb、RBC、PLT及HCT水平。结果 24 h后两组血液标本的MCH、WBC、Hb、RBC、PLT、HCT水平比较差异无统计学意义(P>0.05),但是PLT与HCT水平发生了明显变化。48 h后B组血液标本的Hb、PLT水平高于A组血液标本的Hb、PLT,差异有统计学意义(P<0.05)。结论血液标本置于不同的温度下保存,在不同的时间下血常规水平会出现一定程度的变化,提示临床上需要妥善保存血液标本,选择最佳的检验时间,从而保证血液标本检测结果的可靠性。
Objective To study the influence of different temperature and time on the results of blood routine test. Methods A total of 320 blood samples were collected from July 2014 to July 2015 in health checkup in this hospital. According to the differences in storage temperature, the blood samples were divided into two groups of 160 samples. Group A was stored at room temperature and Group B was refrigerated The levels of MCH, WBC, Hb, RBC, PLT and HCT in the two groups of blood samples were compared and preserved. Results There was no significant difference in the levels of MCH, WBC, Hb, RBC, PLT and HCT between the two groups after 24 h (P> 0.05), but the levels of PLT and HCT were significantly changed. After 48 h, the Hb and PLT levels of blood samples of group B were higher than that of blood samples of group A, and the difference was statistically significant (P <0.05). Conclusion The blood samples were stored at different temperatures, and the blood routine levels changed to some extent at different times, suggesting that blood samples should be properly preserved in clinic and the best test time should be chosen so as to ensure the reliable blood test results Sex.
