## Indications for use
The EUROIMMUN Anti-West Nile Virus ELISA (IgG) is intended for the qualitative detection of IgG antibodies to West Nile virus in human serum and plasma (K+-EDTA, Li+-heparin). This test is intended as an aid in the presumptive laboratory diagnosis of West Nile virus infection in patients with clinical symptoms consistent with meningitis/encephalitis, in conjunction with other laboratory and clinical findings. Positive results must be confirmed by the plaque reduction neutralization test (PRNT) or by using the current CDC guidelines for diagnosis of this disease. The assay characteristics have not been established for testing cord blood, neonates, prenatal screening, and general population screening of patients without symptoms of meningoencephalitis. This assay is not FDA cleared or approved for testing blood or plasma donors. Warning: Cross-reactivity with IgG to Dengue, Chikungunya, Zika and Tick-borne Encephalitis (TBE) viruses has been observed with the EUROIMMUN Anti-West Nile Virus ELISA (IgG). Reactive results must be reported with a caution statement regarding possible IgG cross-reactivity with other flaviviruses.
