Aid in the diagnosis of lymphocytic choriomeningitis (LCM) viral infection.
Semi-Quantitative Indirect Fluorescent Antibody
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min 0.2 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent."
Contaminated, hemolyzed, or severely lipemic specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
|2001633||Lymphocytic Choriomeningitis (LCM) Virus Antibody, IgG||< 1:10 Negative - No significant level of LCM virus IgG antibody detected.
≥ 1:10 Positive - Presence of IgG antibody to LCM virus detected, suggestive of current or past infection.
|2001634||Lymphocytic Choriomeningitis (LCM) Virus Antibody, IgM||< 1:10 Negative - No significant level of LCM virus IgM antibody detected.
≥ 1:10 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.
