Varicalle Zoster Immunity Blood Test (VZV IgG - Chickenpox Immunity)

The Varicalle Zoster Immunity Blood Test is a diagnostic tool designed to determine whether an individual has immunity to chickenpox, a common and highly contagious disease caused by the varicella-zoster virus (VZV).

The test measures the presence of immunoglobulin G (IgG) antibodies in the blood, which are produced in response to a past infection with the VZV or from vaccination. While each provider may offer a slightly different set of biomarkers, the basic test typically covers the detection of VZV IgG antibodies.
