Western Equine Encephalitis Virus (IgG, IgM) Antibody Panel, IFA, CSF
Use
This test may assist in identifying infectious agents causing encephalitis or meningoencephalitis via detection of Western equine encephalitis virus –specific IgG and IgM antibodies in cerebrospinal fluid, providing diagnostic support in CNS infections of arboviral origin.
Special Instructions
Not available for New York State clients. For a complete arbovirus panel, order Arbovirus Antibody Panel, IgG and IgM, Spinal Fluid. If not ordering electronically, complete Infectious Disease Serology Test Request (T916) form and submit with specimen.
Limitations
This immunofluorescent antibody (IFA) assay uses a two‑stage “sandwich” procedure and yields semi‑quantitative endpoint titers; cross‑reactivity with related viruses (e.g., Eastern equine encephalitis, St. Louis encephalitis) may occur. Results must be interpreted in clinical context and other epidemiological data.
