The nickle (Ni) concentrations of blood plasma, urine and scalp hair do not differ between hypersensitive and non-hypersensitive subjects. Those who are occupationally exposed have about ten times the control content of nickel in the plasma, urine and hair, whether hypersensitive or not. During vacations the Ni contents of their plasmas and urines decrease sharply. Oral administration of only 5 mg Ni (as the sulphate) increases the Ni concentration of plasma and urine to ten times the normal for more than the subsequent 24 h.
血浆、尿液和头皮毛发中的镍（Ni）浓度在过敏者和非过敏者之间并无差异。无论是否过敏，职业暴露人群血浆、尿液和毛发中的镍含量约为对照组的十倍。在假期期间，他们血浆和尿液中的镍含量会大幅下降。仅口服5毫克镍（以硫酸盐形式）会使血浆和尿液中的镍浓度在随后的24小时以上增加至正常水平的十倍。
