摘　　要：目的探讨五分类血细胞分析仪血小板参数不全的原因及解决方法。方法对XS-1000i、XT-1800i五分类血细胞分析仪检测血小板参数不全的标本,使用XT-2000i五分类血细胞分析仪网织红细胞计数通道进行复测,并与手工血小板计数比对,推片染色镜检进行红细胞和血小板的形态学观察。结果 3台仪器2种不同检测方法均未能检测出血小板参数;XS-1000i、XT-1800i血小板计数与手工法相比对,二者差异均有统计学意义(P<0.05),XT-2000i网织红细胞计数通道血小板计数与手工法相比对,差异无统计学意义(P>0.05)。结论对无血小板参数的标本使用XT-2000i血细胞分析仪网织红细胞计数通道计数血小板,结果可靠。极端小红细胞和红细胞碎片、血小板形态不齐是引起仪器检测血小板参数不全的主要原因。对无血小板参数的标本,应手工进行红细胞及血小板形态学检查,并加强与临床医生的沟通。Objective To investigate the reasons of platelet parameter incompletion of five categories blood cell analyzer and its solutions.Methods Specimens with incomplete platelet parameters were detected by XS-1000i and XT-1800i five categories blood cell analyzers,and were retested by XT-2000i five categories blood cell analyzer with reticulocyte channel,compared with the results of hand-counting,staining microscopy and morphological observation of red blood cells and platelets.Results The platelet parame-ters were failed to be detected by the three different instruments through two kinds of methods.The results of XS-1000i and XT-1800i five categories blood cell analyzers were significantly different from the result of hand counting（P〈0.05）,while the results of XT-2000i five categories blood cell analyzer was close to the result of hand counting（P〉0.05）.Conclusion It is credible to use re-ticulocyte channel of XT-2000i five categories blood cell analyzer to detect the platelet counts of specimens without platelet parame-ters.The main reasons leading to incomplete platelet parameters are the extreme small red blood cells,red blood cell debris and platelet form of arrhythmia.Manually morphological examination of red blood cells and platelet should be used to detect specimens without platelet parameters.
