West Nile Virus IgG Test

The West Nile Virus IgG Test is a diagnostic tool used to detect IgG antibodies against the West Nile Virus in the bloodstream. The West Nile Virus is a mosquito-borne disease, with a majority of infected individuals experiencing no symptoms. In severe cases, it can lead to inflammation of the brain (encephalitis) or the membranes surrounding the brain and spinal cord (meningitis).

IgG antibodies are typically produced in the later stages of an infection or post-infection, providing long-term immunity. Hence, their presence in the blood usually indicates a past infection with the West Nile Virus.
