A two-site immunoradiometric assay for human ferritin has been developed using antibody-coated polystyrene tubes. Serum ferritin was measured in fifty-four men and women aged 73 years. The geometric mean was 166 micrograms/l for thirty-one men and 161 micrograms/l for twenty-two women. One woman was excluded from the statistical calculations. Twenty-eight of the subjects had earlier participated in a study of food consumption by the duplicate portion technique. There was a significant correlation (r = 0.44, P < 0.01) between the food iron intake and the serum ferritin values. A reference material of men and women aged 18-55 years was also analysed. The geometric mean for males was 170 micrograms/l with a 95% confidence range of 46-637 micrograms/l. The female controls were found to have significantly lower values (geometric mean 51 micrograms/l, 95% confidence range 10-260 micrograms/l) than both the older women (P < 0.001) and the male controls (P < 0.001).
已开发出一种使用抗体包被聚苯乙烯管的人铁蛋白双位点免疫放射分析方法。对54名73岁的男性和女性进行了血清铁蛋白检测。31名男性的几何平均值为166微克/升，22名女性的几何平均值为161微克/升。一名女性被排除在统计计算之外。其中28名受试者早些时候参与了采用双份食物技术的食物摄入量研究。食物铁摄入量与血清铁蛋白值之间存在显著相关性（r = 0.44，P < 0.01）。还对18 - 55岁的男性和女性参考物质进行了分析。男性的几何平均值为170微克/升，95%置信区间为46 - 637微克/升。发现女性对照组的值（几何平均值51微克/升，95%置信区间10 - 260微克/升）显著低于老年女性（P < 0.001）和男性对照组（P < 0.001）。
