仪器是如何进行细胞分群的呢？
۩ 仪器除给出细胞数据结果外，同时提供出 细胞体积分布图形，这些可以表示出细胞 群体分布情况的图形被称为直方图
۩ 它可以显示出某一特定细胞群的平均细胞 体积、细胞分布情况和是否存在明显的异 常细胞群
۩ Hemoglobin (hemoglobin or heme) ۩ Hemoglobin is present in red blood
cells and is a kind of protein containing iron. ۩ Adult male is 120 ~ 160g/L ۩ Adult female is 110 ~ 150g/L
۩ Platelet PLT ۩ Hemoglobin HGB
一、The development history of
blood cell analyzer
۩ In 1956, the American scientist W.H.Coulter patented technology for the use of the resistance method to count the number of particles in the blood cell count to be successful.
