Immunoglobulin levels were estimated in 138 infants, of whom 33 were normal newborn and 105 were healthy infants one to 24 months of age. Most of the newborn were delivered after a normal pregnancy. In all the infants relatively high levels of cord IgM were found. Similarly, relatively high levels of IgA were found in cord blood in 72% of the subjects studied. Physiological hypogammaglobulinaemia was not found in the early months of life. Adult levels of IgM were developed by six months of age while 36% of the adult levels of IgA and 57% of the adult levels of IgG were reached by two years of age.
对138名婴儿的免疫球蛋白水平进行了评估，其中33名是正常新生儿，105名是1至24个月大的健康婴儿。大多数新生儿是在正常妊娠后分娩的。在所有婴儿中，均发现脐带血IgM水平相对较高。同样，在72%的研究对象的脐带血中发现IgA水平相对较高。在生命的最初几个月未发现生理性低丙种球蛋白血症。IgM在6个月大时达到成人水平，而IgA在两岁时达到成人水平的36%，IgG在两岁时达到成人水平的57%。
