About Varicella zoster immunity

What is varicella-zoster?

The varicella-zoster virus causes an infection called varicella, or more commonly known as chickenpox. Chickenpox is typically a childhood illness which can be prevented by vaccination. Chickenpox symptoms include fever and an itchy blister rash. The rash is contagious until the blisters scab over. The varicella-zoster virus can cause shingles in adults who were infected as children causing pain and blisters. Varicella-zoster antibodies are produced by the body’s immune system to help fight infection against the virus. IgG antibodies are a particular type of antibody that offer long-term protection against pathogens after initial exposure. The presence of IgG antibodies indicates immunity. This may be a result of a previous infection or from vaccination.

Why take the test?

This test measures the level of varicella-zoster IgG antibodies in the blood and can be used to check immunity as a result of a previous infection or from vaccination.
