Aid in the diagnosis of measles encephalitis. False-positive results will occur due to low incidence of measles in the U.S.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
New York DOH Approval Status
Transfer 0.5 mL CSF to an ARUP Standard Transport Tube. (Min: 0.2 mL)
Refrigerated. Also acceptable: Frozen.
Contaminated, heat-inactivated, or hemolyzed specimens.
Ambient: 8 hours; Refrigerated: 2 weeks; Frozen: 1 year
|0.79 AU or less||Negative - No significant level of IgM antibodies to measles (rubeola) virus detected.|
|0.80-1.20 AU||Equivocal - Repeat testing in 10-14 days may be helpful.|
|1.21 AU or greater||Positive - IgM antibodies to measles (rubeola) virus detected. Suggestive of current or recent infection or immunization. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection or immunization.|
The detection of antibodies to rubeola 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.
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.
