|2001629||Lymphocytic Choriomeningitis (LCM) Virus Antibody, IgG, CSF||< 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.
|2001630||Lymphocytic Choriomeningitis (LCM) Virus Antibody, IgM, CSF||< 1:1 Negative - No significant level of LCM virus IgM antibody detected.
≥ 1:1 Positive - Presence of IgM 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.
