<=0.99 S/CO
Negative - No significant level of IgG antibody to varicella-zoster virus detected.
>=1.00 S/CO

Interpretive Data
May include disease information, patient result explanation, recommendations, or details of testing.
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.
