Indirect Fluorescent Antibody (IFA)
A positive result for IgG may suggest current or past infection. Eastern equine encephalitis and western equine encephalitis viruses are both related and will show cross-reactivity. Initial infection by one of these viruses will show a specific rise in titer which is higher than titers against any other viruses of the group. A subsequent infection by another virus within this group, however, will boost the titer against the initial infecting virus (anamnestic response) and make a specific diagnosis difficult.
