Antigen Testing for Accuracy
Evaluate Fever, Fatigue
Comprehensive testing for active or recent West Nile virus infection using antigen and antibody markers, with personalized provider review.
West Nile virus is transmitted through mosquito bites and can range from mild flu-like illness to severe neurologic complications. Early and precise testing helps guide monitoring and care.
West Nile Antigen – Detects active viral presence in the early phase of infection.
West Nile IgM Antibody – Identifies recent infection and early immune response, typically within the first week of symptoms.
West Nile Antibody Testing (Serology) – Evaluates immune response to determine recent or prior exposure.
Most tests only detect active infection. This panel evaluates immune response and recovery status.
Fasting is not required.
Most results return within 2–5 business days.
Testing is most accurate within the first week of symptom onset; your provider will advise timing.
Antibody testing can indicate recent or prior exposure depending on results and timing.
