A commercial assay for detection of measles immunoglobulin G (IgG) in oral fluid was evaluated in a highly vaccinated cohort using serum IgG as gold standard. In contrast to previous studies from cohorts protected by natural immunity, antibody prevalence was significantly underestimated (-7.4%; confidence interval: -1.5 to -13.2%; P = 0.01) due to a reduced sensitivity when antibody levels were low.
在一个高疫苗接种率队列中,以血清IgG作为金标准,对一种用于检测口腔液中麻疹免疫球蛋白G(IgG)的商业检测方法进行了评估。与之前来自受自然免疫保护队列的研究不同,由于抗体水平较低时灵敏度降低,抗体流行率被显著低估(-7.4%;置信区间:-1.5至-13.2%;P = 0.01)。
