|Interpretive Data:||Please see report for interpretive data.|
West Nile Antibody IgG:
WNV IgG may produce false positive results due to cross-reactivity to CMV and/or bunyaviruses, or if a person has been infected with or vaccinated for flaviviruses such as Japanese encephalitis virus, dengue virus, or yellow fever virus.
West Nile Antibody IgM:
WNV IgM may produce false positive results due to other flaviviruses or residual IgM from previous infection present for over 500 days. IgM positive results for children may also be caused by cross-reactivity with enteroviruses.
