目前临床普遍采用全自动血细胞分析仪检测血小板,所用的抗凝剂为国际血液学标准化委员会推荐的对血细胞计数影响较小的EDTA盐。但是,在某些情况下,EDTA盐会引起血小板在体外发生聚集。由于聚集后的血小板体积增大,使血细胞计数仪将血小板误作白细胞计数,引起血小板假性减少,白 At present, the platelet is generally detected by automatic hematology analyzer. The anticoagulant used is the EDTA salt recommended by the International Commission of Hematology Standardization who has little effect on the blood count. However, in some cases EDTA salts cause platelets to aggregate in vitro. Due to the increased volume of platelets after aggregation, the hemocytometer mistakenly counts platelets for white blood cells, resulting in a diminished platelet count and white
