FAQ
Frequently asked questions
What is the difference between VZV IgG and IgM?
IgG antibodies are typically present long-term after an infection or vaccination and indicate immunity. IgM antibodies are usually present during a recent or active infection.
Can this test detect shingles?
This test detects antibodies related to the Varicella Zoster Virus, which causes both chickenpox and shingles. It indicates immunity to the virus, not necessarily an active shingles infection.
How soon after exposure or vaccination can the test detect immunity?
It can take several weeks after a chickenpox infection or vaccination for IgG antibody levels to become detectable. Your healthcare provider can discuss the best timing for testing.
What does it mean if my VZV IgG test is negative?
A negative result suggests you may not have immunity to the Varicella Zoster Virus. This could mean you have not had chickenpox and were not vaccinated, or your immunity has waned.
