摘要
目的：探讨血常规检验中的误差以及影响因素。方法选取2014年7月至2015年1月在我院治疗的患者血常规检查标本304例,在不同储存温度、放置时间、抗凝剂浓度等条件下检测血常规标本。结果当储存温度条件为常规温度（6~25℃）时,白细胞含量为（4.42±0.63）×10^9/L,明显高于4℃时,而血小板含量为（210.41±7.93）×10^9/L,明显低于4℃时（P〈0.05）；常规温度和4℃条件下红细胞和血红蛋白含量差异比较无统计学意义（P〉0.05）；放置4h后白细胞含量为（2.92±0.77）×10^9/L,明显低于即时和2h后检测数值,而血小板含量为（303.22±21.04）×10^9/L,明显高于即时和2h后检测数值（P〈0.05）；即时检测红细胞和血红蛋白含量分别为（4.45±0.52）×10^9/L和（119.02±23.06）g/L,明显低于2h和4h后检测数值（P〈0.05）；抗凝剂浓度为2.4mg/ml时,MCV和Hct分别为（89.32±7.05）fl和（0.441±0.012）,明显高于抗凝剂浓度为1.6mg/ml和2.0mg/ml时。结论血液标本保存温度、测定时间以及抗血凝剂浓度均会影响血常规标本检测值,故医护人员应严格按照相关规定进行检测。
Objective To investigate clinical blood test error and influencing factors. Methods Selected from 2014 Ju-ly to 2015 January in our hospital treatment of 304 cases of patients blood routine examination samples, and detected blood rou-tine samples in the different storage temperature, storage time, anticoagulant concentration conditions. Results When the stor-age temperature conditions for the normal temperature（6~25℃）, white blood cell content was （4. 42±0. 63） ×10^9/L, signifi-cantly higher than that of 4℃ and platelet content was （210. 41±7. 93）×10^9/L, significantly lower than that of 4℃（P〈0. 05）. The differences of red blood cell and hemoglobin in the conventional temperature and 4℃ was no statistical significance （ P〉0. 05）. After placing 4h white blood cell content was （2. 92±0. 77）×10^9/L, significantly lower than that of real-time and 2h de-tection value, and platelet content was （303. 22±21. 04）×10^9/L, significantly higher than that of real-time and 2h detection val-ue （P〈0. 05）. Real-time detection of red blood cell and hemoglobin content were （4. 45±0. 52）×10^9/L and （119. 02±23. 06） g/L, significantly lower than that of 2h and 4h（P〈0. 05）. When the anticoagulants concentration was 2. 4mg/ml, MCV and Hct were （89. 32±7. 05） fl and （0. 441±0. 012）, significantly higher than that of the concentration of 1. 6mg/ml and 2. 0mg/ml. Conclusion Blood samples storage temperature, determination time and the anti coagulant concentration will affect the blood samples detection value, so the medical staff should test strictly in accordance with the relevant provisions.
