Michel等已证实脐带血IgE是由胎儿来的,其浓度超过1U/ml是婴儿特应性疾病易感性的预兆。作者收集660份出生第5天的婴儿血标本。结合筛查试验,诸如苯丙酮尿病和甲状腺疾病筛查,用“Phadebas Prist”测定IgE水平。到出生后1个月时,对血清IgE值>1U/ml(“阳性”)的婴儿进行随访,并对IgE<1U/ml的婴儿随机取样。查明摄入食物和临床资料。在660名受试婴儿中,61名(9.8%)筛查阳性。到1个月时,筛查阳性的61名中有37名,筛查阴性的61名中23名进行了随访(见表)。这些资料表明IgE筛查确有预测价值。IgE筛查
Michel et al. Have demonstrated that cord blood IgE is produced by the fetus and that concentrations greater than 1 U / ml are predictive of the susceptibility of atopic disease in infants. The authors collected 660 blood samples from infants on the fifth day of life. IgE levels are determined using “Phadebas Prist” in combination with screening tests, such as screening for phenylketonuria and thyroid disease. At one month after birth, infants with serum IgE> 1 U / ml (“positive”) were followed up and infants with IgE <1 U / ml were randomized. Identify food intake and clinical information. Of the 660 infants tested, 61 (9.8%) were positive for screening. By 1 month, 37 of the 61 screening positives and 23 of the 61 screening negatives were followed (see table). These data suggest that IgE screening does have predictive value. IgE screening
