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.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
|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.
|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.
