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.
Interpretive Data
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.
