Semi-Quantitative Enzyme-Linked Immunosorbent Assay
New York DOH Approval Status
Transfer 0.5 mL CSF to an ARUP Standard Transport Tube. (Min: 0.3 mL)
Bacterially contaminated, heat-inactivated, hemolyzed, or xanthochromic specimens.
Ambient: 8 hours; Refrigerated: 2 weeks; Frozen: 1 year
|0.90 ISR or less||Negative - No significant level of IgM antibody to varicella-zoster virus detected.|
|0.91-1.09 ISR||Equivocal - Repeat testing in 10-14 days may be helpful.|
|1.10 ISR or greater||Positive - Significant level of IgM antibody to varicella-zoster virus detected, which may indicate current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.|
The detection of antibodies to varicella-zoster 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.
