Of 1,500 volunteers aged 65 or more selected at random in the Negev area, 224 were found to be healthy and available for further examination. The population represented broadly the various ethnic groups among Jews in Israel. The mean hemoglobin level, hematocrit, red and white blood cell counts and differential count showed no differences other than those due to chance when compared with the corresponding values in a younger (20 to 48 years of age) group. The differences between men and women were similar to those found in the comparison group, with men having higher mean values for hemoglobin, hematocrit, and red blood cell count; in the study group, serum iron, total iron-binding capacity and percent saturation were higher in men in all age groups. No differences were found in mean values of white blood cell count and differential count within the study population. However, mean serum iron was lower, and mean platelet count, higher than in the younger comparison group. This survey supports the use of normal standards for adults when elderly patients are examined, regardless of different ethnic origin. However, the higher than normal platelet counts in subjects from Asia, Africa and Eastern Europe should be taken into account.
在内盖夫地区随机挑选的1500名65岁及以上的志愿者中，发现224人身体健康，可供进一步检查。该人群广泛代表了以色列犹太人中的各个族群。与较年轻（20至48岁）组的相应值相比，平均血红蛋白水平、血细胞比容、红细胞和白细胞计数及分类计数除了因偶然因素外没有差异。男性和女性之间的差异与对照组中发现的差异相似，男性的血红蛋白、血细胞比容和红细胞计数平均值较高；在研究组中，所有年龄组男性的血清铁、总铁结合力和饱和度百分比均较高。研究人群中白细胞计数和分类计数的平均值没有差异。然而，平均血清铁较低，平均血小板计数高于较年轻的对照组。这项调查支持在检查老年患者时使用成人正常标准，无论其种族出身如何。然而，应考虑到来自亚洲、非洲和东欧的受试者血小板计数高于正常水平。
