Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Specimens from New York clients will be sent out to a New York DOH approved laboratory.
Effective January 17, 2012
|Japanese Encephalitis Virus Antibody IgM
|3.9 IV or less
||Negative - No significant level of detectable Japanese encephalitis virus (JEV) IgM antibody.
|4.0 -6.0 IV
||Equivocal - Questionable presence of JEV IgM antibody. Repeat testing in 10-14 days may be helpful.
|6.1 IV or greater
||Positive - JEV IgM antibody detected, which may indicate a current or recent infection. A low IgM antibody level may occasionally persist for more than 12 months post-infection.
A positive result does not necessarily rule out infection with a different Flavivirus spp. The best evidence of current infection is a significant change on two appropriately timed specimens with both tests performed in the same laboratory at the same time.
