"Laborskel-analyzer" (PSL-1) was used to estimate red blood cell volume for the differential diagnosis in 36 polycythemia vera, 20 erythrocytosis patients and 30 normal subjects. Erythrocyte count of polycythemia vera patients (I, IIA and IIB stages) showed a shift to the left (an increase of microcytic fractions), while erythrocyte count++ of 20 erythrocytosis patients (16 of them with a relative erythrocytosis and 4 with an absolute erythrocytosis) were close to erythrocyte count++ of normal subjects. The counting of the percent content of erythrocytic fractions of varying volumes has proved fraction 5 with the erythrocytic volume from 56 microns 3 to 62 microns 3 to have the highest information content. The percent content of this fraction in polycythemia vera fluctuated from 3.9 to 19.5%, and in erythrocytosis it was from 0.9 to 3.0%, that could serve as a criterion for the differential diagnosis of polycythemia vera and erythrocytosis.
使用“Laborskel分析仪”（PSL - 1）对36例真性红细胞增多症患者、20例红细胞增多症患者和30名正常受试者进行红细胞体积估计，以用于鉴别诊断。真性红细胞增多症患者（I、IIA和IIB期）的红细胞计数显示向左偏移（小细胞分数增加），而20例红细胞增多症患者（其中16例为相对性红细胞增多症，4例为绝对性红细胞增多症）的红细胞计数与正常受试者的红细胞计数相近。不同体积红细胞分数的百分比含量计数已证明，红细胞体积为56立方微米至62立方微米的第5部分具有最高信息含量。该部分在真性红细胞增多症中的百分比含量在3.9%至19.5%之间波动，在红细胞增多症中为0.9%至3.0%，这可作为真性红细胞增多症和红细胞增多症鉴别诊断的标准。
