Not recommended as a stand-alone test. Panel that includes lymphocytic choriomeningitis (LCM) virus IgG and IgM antibodies is preferred; refer to Lymphocytic Choriomeningitis (LCM) Virus Antibodies, IgG & IgM, CSF (2001628).
Semi-Quantitative Indirect Fluorescent Antibody
Transfer 0.75 mL CSF to an ARUP Standard Transport Tube. (Min 0.2 mL)
Contaminated, heat-inactivated, or hemolyzed specimens.
Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
< 1:1 Negative - No significant level of LCM virus IgG antibody detected.
≥ 1:1 Positive - Presence of IgG antibody to LCM virus detected, suggestive of current or past infection.
The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
