Order Varicella VZV Titer Test | Chicken Pox IgG Immunity TestingThe Varicella VZV Titer Test measures IgG antibodies against the varicella-zoster virus, the pathogen responsible for chickenpox and shingles. Because IgG antibodies persist after either natural infection or vaccination, this blood test can indicate whether a person carries immunological memory to VZV. It is a serological tool, not a diagnostic test for active disease.
About Varicella VZV Titer Test | Chicken Pox IgG Immunity Testing in Brea
Varicella-zoster virus is a highly contagious herpesvirus. Primary infection typically presents as chickenpox, while reactivation of latent virus later in life causes herpes zoster, commonly known as shingles.
After exposure, the immune system produces IgM antibodies early in infection and IgG antibodies that appear shortly afterward and remain detectable for decades. A positive IgG result generally reflects prior infection or vaccination, though it does not distinguish between the two.
The test is often used to assess immunity in people with uncertain histories, such as those without documentation of chickenpox or vaccination, or in certain occupational and clinical settings where evidence of protection is useful. It may also be ordered before immunosuppressive therapy or during pregnancy to evaluate susceptibility.
Results are reported as positive, negative, or equivocal, sometimes with numeric values. A negative result suggests no detectable IgG and possible susceptibility, while equivocal results may warrant repeat testing. Because antibody levels can wane over time, a negative titer does not always mean a person lacks cellular immunity. Clinical interpretation should account for individual history and context.
