摘　　要：目的探讨末梢血预稀释模式（PD）和静脉血全血模式（WD）的血常规检测结果的差异。方法运用SysmexKX-21N细胞分析仪测定了86例门诊患者及体检者的预稀释末梢血和静脉全血的血常规，对2种方法所测得19项参数结果进行配对t检验和“相差指数”分析。结果配对t检验WBC、RBC、HGB、MCV、MCH、MCHC、PLT、RDW．SD、PDW、MPV、P-LCRs十一项参数P〈0.01，HCT、LYM％、LYM三项P〈0．05，MXD％、NEUT％、MXD、NEUT、RDW。CV五项P〉0．05；“相差指数”分析RBC系相差较小，90％～100％的结果“相差指数”〈10％，WBC及PLT相差系较大。配对t检验与“相差指数”分析结果之间不一致，但2种方法所测得的主要参数结果均符合临床要求。结论血常规测定时应根据实际情况选择标本采集方法和模式，遇到可疑结果要手工复查。Objective To analyze the difference of blood routine assay results between pre-dilution mode of peripheral blood and venous whole blood mode. Methods Blood routine assay of pre-diluted peripheral blood and venous whole blood obtained from 86 patients and health examination persons were examined by Sysmex KX-21N blood cell analyzer. The results of nineteen parameters were analyzed by pairing test and phase contrast analysis, Results When analyzed via pairing t test, of which the WBC, RBC, HGB, MCV, MCH, MCHC, PLT, RDW-SD, PDW, MPV and P-LCR were P 〈 0.01 and of which the HCT, LYM% and LYM were P 〈 0.05,while of which the MXD% , NEUT% , MXD, NEUT and RDW-CV were P 〉 0.05. The phase contrast a- nalysis of RBC series had smaller difference and phase contrast index of 90%-100% results were smaller than 10% , while the phase contrast of WBC and PLT series had big difference. There were some discordance between the phase contrast results and paring t test results, but the main results of two methods can be accepted by clinical. Conclusions The method of blood collec- tion and the mode should be performed according to the practical condition when making the blood routine assay. The results should be analyzed and suspicious one should be rechecked manually.
