Test Overview
Semi-Quantitative Chemiluminescent Immunoassay
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.
0.99 S/CO or less: Negative - No significant level of detectable varicella-zoster IgG antibody.
1.00 S/CO or greater: Positive - IgG antibody to varicella-zoster detected, which may indicate a current or past varicella-zoster infection.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
