Japanese Encephalitis Virus Antibodies, IgG and IgM by ELISA
2005689
Ordering Recommendation
Detect presence of Japanese encephalitis-related IgG and IgM antibodies in individuals with evidence of acute encephalitis syndrome (AES) who have recently traveled to or resided in an endemic country in Asia or the western Pacific. Recommend co-testing for other flaviviruses (eg, dengue fever virus) due to coexistence and antibody formation interference in previously flavivirus-infected individuals.
