Key facts

  • Arbovirus identified in Serum by Immunofluorescence
  • Arbovirus
  • The presence of clinically relevant mosquito-borne viruses, including Eastern Equine Encephalitis (EEE), St. Louis Encephalitis (SLE), Western Equine Encephalitis (WEE), and California Encephalitis (CE) group viruses, is determined by qualitative detection of human Arbovirus IgG antibodies to each of the viruses. This code is used to report the arbovirus identified. Clinical correlation is necessary. This term was created for, but not limited in use to, the submitter's reporting style for Focus Diagnostics' Arbovirus IgM Indirect Immunofluorescent Antibody IFA) assay.
