If ordered in workup of possible varicella-zoster infection, the IgG antibody results should be interpreted in conjunction with other laboratory tests, clinical history, and physical examination. Medicine Baltimore. What does an equivocal result mean? Varicella-zoster virus VZV is a member of the Herpesviridae family and causes chickenpox varicella and herpes zoster shingles [ 1 ]. During reactivation, the virus migrates along neural pathways to the skin, producing a unilateral rash, usually limited to a single dermatome. AI values above the manufacturer recommended cutoff for this assay indicate that specific antibodies were detected, suggesting prior exposure or vaccination.
