Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Transfer 0.5 mL CSF to an ARUP Standard Transport Tube. (Min: 0.3 mL)
Specimen types other than CSF. Contaminated, heat-inactivated, or hemolyzed 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.
