West Nile Serum Interpretation
Use
The test assists in the interpretation of IgM and IgG antibodies for the laboratory diagnosis of infection with West Nile virus (WNV). WNV is a mosquito-borne flavivirus that primarily infects birds but can also infect humans and horses. The infection can range from asymptomatic to West Nile fever, with severe cases potentially leading to neuroinvasive diseases or affecting older patients more severely.

Limitations
Results must be interpreted in conjunction with clinical evaluation and other diagnostic procedures. Negative results in immunosuppressed patients have uncertain significance. False positives may occur due to cross-reactivity with other flaviviruses or arboviruses. Specimen contamination during lumbar puncture can also cause erroneous results. Antibody levels in CSF should be carefully interpreted.
