134 IV or less: Negative - No significant level of IgG antibody to varicella-zoster virus detected.
135 - 165 IV: Equivocal - Repeat testing in 10 - 14 days may be helpful.
166 IV or greater: Positive – IgG antibody to varicella-zoster virus detected, which may indicate a current
or past varicella-zoster infection.
