West Nile Virus (WNV) Antibody, IgG and IgM

Laboratory: Labcorp
Test code: 138842
Specimen: Serum
Fasting: Not stated
LOINC: 94854-7
Turnaround: 1 - 4 days

Laboratory assay overview

This test is indicated for use as an aid to the diagnosis of West Nile virus encephalitis. WNV IgM antibodies typically appear three to eight days after illness onset and persist 30 to 90 days (but can persist up to 500 days). WNV IgG antibodies appear shortly after IgM antibodies and persist greater than 500 days. Due to cross-reactivity with other flaviviruses, confirmation by neutralizing antibody assay may be recommended.

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.

Always review your personal lab results with a licensed clinician, or track your lab history and health goals in Aumnivida.
