A) Frequency of IgG reactivity of clinically defined samples and serologically defined VZV-IgG/IgM negative samples, (*) as assayed by Enzygnostic wcELISA, to selected recombinant VZV antigens . B) Frequency of IgM reactivity of clinically defined samples and serologically defined VZV-IgG/IgM negative samples, (*) as assayed by Enzygnostic wcELISA, to selected recombinant VZV antigens. C) Frequency (%) of reactive serum samples (IgG) against specific VZV antigens in a panel of 100 blood donors grouped according to age. Single VZV antigen bands were considered as positive when their intensity was higher than the cut-off band control.
