巨幼细胞贫血:全血细胞计数显示MCV(红细胞平均体积)明显升高


全血细胞计数显示MCV(红细胞平均体积)明显地升高,是典型的巨幼细胞贫血的表现。失血或溶血性贫血恢复期,MCV可略微升高。这是因为新释放的红细胞,网织红细胞,比正常红细胞体积大。而当其成熟后,体积会轻微减小。
The CBC here shows a markedly increased MCV, typical for megaloblastic anemia. The MCV can be mildly increased in persons recovering from blood loss or hemolytic anemia, because the newly released RBC's, the reticulocytes, are increased in size over normal RBC's, which decrease in size slightly with aging.
