IgG subclass levels were determined in 128 apparently normal Nigerian subjects aged 6--42 years, using a modified radial immunodiffusion technique. IgG1 constituted the major subclass with about 70% of the total IgG. IgG4 subclass was the least with about 0.5%. The concentrations of IgG2 and IgG3 were 27% and 1.5% of the total IgG respectively. There was no systematic effect of age on all the subclasses. IgG1 and IgG2 levels were higher in females than in males but there were no marked differences in the IgG3 and IgG4 levels between the sexes.
采用改良的放射免疫扩散技术，对128名年龄在6至42岁之间、表面上健康的尼日利亚受试者测定了IgG亚类水平。IgG1是主要亚类，约占总IgG的70%。IgG4亚类最少，约占0.5%。IgG2和IgG3的浓度分别占总IgG的27%和1.5%。年龄对所有亚类均无系统性影响。女性的IgG1和IgG2水平高于男性，但两性之间的IgG3和IgG4水平无明显差异。
