不同采血方法在血常规检验中的应用价值研究

目的 研究不同采血方法对血常规检验的影响。方法 选取2015年10月~2017年10月我中心进行血常规检验的96例患者作为研究对象，随机分为A、B、C三组，每组32例。A组采用动脉采血方法，B组采用静脉采血方法，C组采用末梢采血方法。对比三组患者血常规检查情况，分析三种采血方法对血常规检验结果的影响。结果 A、B两组患者血常规检查WBC、RBC、PLT、Hb、HCT、MCV、MCH以及MCHC水平对比，差异无统计学意义（P＞0.05）；C组患者MCH水平与A、B两组比较，差异无统计学意义（P＞0.05）；C组患者WBC、MCV水平高于A、B两组，RBC、PLT、Hb、HCT、MCHC水平低于A、B两组，差异有统计学意义（P＜0.05）。C组患者血常规WBC、RBC、PLT、Hb、HCT、MCV、MCH以及MCHC平均CV值高于A、B两组，差异有统计学意义（P＜0.05）。结论 静脉采血和动脉采血的血常规检验结果相似，较为准确，便于临床应用，静脉采血可在临床推广使用。

Study on the Application Value of Different Blood Collection Methods in Blood Routine Examination

Objective To study the effects of different blood collection methods on blood routine tests. Methods A total of 96 patients who underwent routine blood tests from October 2015 to October 2017 were randomly divided into three groups: A, B, and C, with 32 patients in each group. Group A was treated with arterial blood collection, group B was treated with venous blood collection, and group C was treated with peripheral blood collection. The blood routine examination of the three groups of patients was compared, and the effects of the three blood collection methods on the blood routine test results were analyzed.Results There were no significant differences in WBC, RBC, PLT, Hb, HCT, MCV, MCH and MCHC between the two groups (P>0.05). The MCH levels in group C were compared with those in groups A and B,the difference was not statistically significant (P>0.05). The levels of WBC and MCV in group C were higher than those in group A and B. The levels of RBC, PLT, Hb, HCT and MCHC were lower than those in groups A and B,the difference was statistically significant. (P<0.05). The mean CV values of blood routine WBC, RBC, PLT, Hb, HCT, MCV, MCH and MCHC in group C were higher than those in group A and B,the difference was statistically significant (P<0.05).Conclusion The routine blood test results of venous blood collection and arterial blood collection are similar, accurate and convenient for clinical application. The venous blood collection can be used in clinical practice.
