Test ID: FNMEN    
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.
