The content of S, Ca, Fe, Cu and Zn in the finger-nails of 17 women with iron deficiency was examined by X-ray microanalysis and compared with that of 17 healthy women. The values for all these elements were similar in both groups. The distribution curve for iron was also similar in both patients and controls. There was no correlation between the iron content of the finger-nails and the serum iron or haemoglobin levels. It is suggested that the iron content of the finger-nails in iron deficient patients does not reflect their iron status.
采用X射线微量分析法检测了17名缺铁女性指甲中硫、钙、铁、铜和锌的含量，并与17名健康女性的指甲进行了比较。两组中所有这些元素的值相似。患者和对照组的铁分布曲线也相似。指甲中的铁含量与血清铁或血红蛋白水平之间没有相关性。提示缺铁患者指甲中的铁含量不能反映其铁状态。
