|Japanese Encephalitis Virus Antibody IgG
|1.9 IV or less
||Negative - No significant level of detectable Japanese encephalitis virus (JEV) IgG antibody.
|2.0 - 4.9 IV
||Equivocal - Questionable presence of JEV IgG antibody. Repeat testing in 10-14 days may be helpful.
|5.0 IV or greater
||Positive - JEV IgG antibody detected, which may indicate a current or past infection.
A positive result does not necessarily rule out infection with a different Flavivirus spp. Patients in the early stage of JEV infection may not have a detectable level of IgG antibody; IgG response may take several days or weeks to develop. In the absence of detectable IgG, testing for IgM-class antibody is strongly recommended. 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.
