The varicella-zoster virus (VZV) is responsible for causing two distinct diseases: chickenpox (varicella) and shingles (herpes zoster). Chickenpox is highly contagious and characterized by an itchy skin rash. Shingles is characterized by a painful rash and occurs when the virus reactivates from a dormant state within nerve cells.

Immunity to the varicella-zoster virus can be assessed with eNational’s blood test.

Who should take this test?

This test is used to assess immunity to the varicella-zoster virus, either from a previous infection or vaccination, and is appropriate for anyone concerned about their susceptibility to VZV infection. It is not used to diagnose an active infection with either chickenpox or shingles.

What is included in this test?

This blood test screens for:

• VZV IgG antibodies

This test detects the presence of IgG antibodies, which typically remain in the bloodstream for years, providing long-term immunity against VZV.

How will taking this test benefit me?

Confirming your immunity to VZV can provide peace of mind before entering high-risk environments. A booster vaccine may be recommended if antibody levels are insufficient.
