Clinical Info

The detection of antibodies to VZV 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. Interpretation: Negative: <=0.90 ISR; 0.91-1.09 ISR: Equivocal; 1.10 or greater ISR: Positive - Significant level of IgM antibody to VZV detected, which may indicate current or recent infection. However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.
