Interpretation guide:
Negative Absence of detectable VZV IgG antibodies. A negative result indicates no detectable VZV antibody but does not rule out acute infection. It should be noted that the test usually scores negative in infected persons during the incubation period and the early stages of infection. If exposure to varicella zoster virus is suspected despite a negative finding, a second sample should be collected and tested no less than one or two weeks later.
Equivocal Suggest a second sample be collected and tested one to two weeks later.
Positive Presence of detectable VZV IgG antibodies. A positive result generally indicates exposure to the pathogen or administration of specific immunoglobulins, but it is no indication of active infection or stage of disease.
NOTE: This test is for the qualitative determination of IgG antibodies to varicella zoster virus.
