title: Evaluation of commercial assay detecting specific immunoglobulin g in oral fluid for determining measles immunity in vaccinees.
abstract: 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.
