Testing for Arbovirus antibodies on serum and/or CSF are currently not being performed in the United States due to a nationwide shortage of reagent. Marshfield Labs will store samples frozen for testing when the reagent becomes available again.
West Nile Virus Antibody IgG & IgM on serum (test code WNVSO) and CSF (test code WNCSFSO) are available through Marshfield Labs.
