Clinical Significance
Varicella-Zoster Virus Antibody (IgG) - Varicella-Zoster Virus (VZV) causes chicken pox and when reactivated, potentially decades later, causes shingles. Twenty percent of adults will develop shingles, a rash or blister of the skin that may cause severe pain. Varicella-Zoster IgG, Immunoassay reliably measures immunity due to previous infection, but is unsuitable for detection of post-vaccination immune status.
