We studied 36 men and 94 women aged 60 to 85 years, without nutritional deficiencies or illness that could interfere with hematopoiesis, to characterize the normal limits of red and white blood cell counts. Lower limit of hemoglobin normal values were 132 g/l for men and 125 g/l for women. The corresponding figures for MCV were 85 fl and 83 fl for men and women respectively. Lower and upper normal limits for leukocyte count in both sexes were 3.66 and 9.36 x 10(9)/l. Hypersegmented neutrophils existed in 7% of men and 14% of women in spite that folate and vitamin B12 deficiencies were excluded. We concluded that blood cell counts of elderly people have mild deviations of normal values for young adults. Aged humans have a low white cell and bands counts, and elderly women have a higher hemoglobin concentration.
我们研究了36名男性和94名年龄在60至85岁之间的女性，这些人没有可能干扰造血的营养缺乏或疾病，以确定红细胞和白细胞计数的正常范围。男性血红蛋白正常值下限为132 g/l，女性为125 g/l。男性和女性的平均红细胞体积（MCV）相应数值分别为85 fl和83 fl。两性白细胞计数的正常下限和上限分别为3.66和9.36×10⁹/L。尽管排除了叶酸和维生素B12缺乏，但7%的男性和14%的女性存在多分叶核中性粒细胞。我们得出结论，老年人的血细胞计数与年轻人的正常值有轻微偏差。老年人白细胞和杆状核细胞计数较低，老年女性血红蛋白浓度较高。
