[摘要] 目的:探讨静脉防凝全血、手指末梢防凝全血和手指末梢稀释血三种采血模式在全自动血液分析仪上血细胞测定的结果差别。方法:肘静脉血、手指末梢血用EDTA-K2防凝,手指末梢血用稀释液1∶26稀释,分别用全血模式和稀释模式测定结果。结果:肘静脉防凝全血、手指末梢防凝全血、手指末梢稀释血三者的白细胞(WBC)、红细胞(RBC)、血红蛋白(HCG)、红细胞比容(HCT)的结果均无显著性差异,但在血小板(PLT)结果中,前两种防凝血结果差异无统计学意义,而均与手指末梢稀释血结果有显著性差异。结论:在一定条件下,可用手指末梢防凝全血替代肘静脉防凝全血进行血液测定;手指末梢稀释血结果不稳定,不建议使用。

[Abstract] Objective: To investigate the difference of three blood collection models that are determined by automatic hematology analyzer. Methods: Venous blood, peripheral blood from finger was treated with anticoagulant(EDTA-K2) to prevent clotting of blood; meanwhile, peripheral blood from finger was diluted by dilute liquid(1∶26) ......
