Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Transfer 0.5 mL CSF to an ARUP Standard Transport Tube. (Min: 0.2 mL)
Refrigerated. Also acceptable: Frozen.
Specimen types other than CSF. Contaminated, heat-inactivated, or hemolyzed specimens.
Ambient: 8 hours; Refrigerated: 2 weeks; Frozen: 1 year
|0.79 IV or less||Negative - No significant level of detectable IgM antibody to Mumps virus.|
|0.80-1.20 IV||Equivocal - Borderline levels of IgM antibody to Mumps virus. Repeat testing in 10-14 days may be helpful.|
|1.21 IV or greater||Positive - Presence of IgM antibody to Mumps virus detected, which may indicate a current or recent infection. However, low levels of IgM antibody may occasionally persist for more than 12 months post-infection or immunization.|
The detection of antibodies to mumps in CSF may indicate central nervous system infection. However, consideration must be given to possible contamination by blood or transfer of serum antibodies across the blood-brain barrier.
