Neisseria Meningitidis IgG Vaccine Response
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Reference Ranges (pre-vaccination):
Serogroup A <4.0 ug/mL
Serogroup C <5.0 ug/mL
Serogroup Y <4.0 ug/mL
Serogroup W-135 <3.0 ug/mL
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 sero-
groups 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.
