Serotypes A, C, Y, W-135
Multi-Analyte Immunodetection (MAID)
This assay measures serum IgG antibodies recognizing polysaccharide antigens from the four Neisseria meningitidis
serogroups included in the licensed meningococcal vaccine. The
meningococcal vaccine response is best evaluated by testing
pre-vaccination and post-vaccination samples in parallel. A two-fold or
greater increase for at least two serogroups is expected when comparing
post-vaccination to pre-vaccination results. N. Meningitidis IgG levels peak approximately one month post-vaccination, but decline markedly by two years.
