Coulter model S blood counts were related to the age, sex, and smoking habits of 1,000 clinic patients. It was found that (1) women have larger erythrocytes than men; (2) erythrocytes enlarge as people age; (3) smokers have larger erythroycytes than nonsmokers; (4) the mean leukocyte count is higher in smokers and increases in proportion to the intensity of smoking. The causes of these alterations are not known. The data indicate that the normal standards for blood cell counts should be adjusted for age, sex, and smoking habits.
库尔特S型血细胞计数与1000名门诊患者的年龄、性别和吸烟习惯有关。结果发现：（1）女性的红细胞比男性的大；（2）红细胞随着年龄增长而增大；（3）吸烟者的红细胞比不吸烟者的大；（4）吸烟者的平均白细胞计数较高，且与吸烟强度成正比增加。这些变化的原因尚不清楚。数据表明，血细胞计数的正常标准应根据年龄、性别和吸烟习惯进行调整。
