What This Test Measures
This test measures IgG antibodies to Varicella Zoster Virus (VZV) only. VZV is a member of the herpes virus family and is the virus responsible for chickenpox and, later in life through reactivation, shingles. This test detects whether your body has produced IgG antibodies to VZV, which typically develop several weeks after initial infection and can also result from vaccination.
The presence of VZV IgG antibodies reflects your body's immune response to the virus, but this test alone does not distinguish between a past infection and a current active infection. Interpretation of your result should take into account your symptoms, history, and other clinical findings, and this test does not independently confirm or rule out a diagnosis.

FAQ
1. What is the purpose of this IgG antibody test?
This test measures IgG antibodies to Varicella Zoster Virus (VZV) to help a healthcare provider evaluate your history of exposure to the virus through past infection or vaccination. It is not a panel and does not test for other antibody types. This test alone does not diagnose an active infection or confirm immunity, and results should be reviewed with a healthcare provider alongside your symptoms and history.
2. Who would benefit from this test?
This test may be useful for individuals who want to check their VZV antibody status, including those uncertain of their chickenpox history or vaccination status, and people with weakened immune systems who want more information about their VZV status. It may also be relevant for pregnant individuals discussing VZV with their provider.
3. When should I order this test?
You may consider ordering this test if you want to review your history of exposure to VZV through past infection or vaccination. It can support broader conversations with your healthcare provider about your VZV status. This test does not replace a full medical evaluation and should be considered alongside your symptoms and history.
4. Does this test measure other antibody types?
This test measures only VZV IgG antibodies. It does not measure IgA, IgM, IgE, or IgD antibodies. It also does not measure total IgG or IgG subclasses. An IgG result reflects a different stage of immune response than an IgM result and does not provide the same information as testing for other antibody classes.
5. Do I need to fast before this test?
No special preparation is required for this test.
6. How quickly will I get results?
Results are typically available in 2-3 days. Results may take longer based on weather, holiday, or lab delays.
7. How do I interpret the results?
The meaning of your VZV IgG result depends on your symptoms, medical history, exposure history, timing, and any other test results your provider may consider. A positive result does not automatically confirm an active infection, and it may reflect past infection or vaccination depending on the clinical picture. A negative result does not necessarily rule out prior exposure. Your healthcare provider is best positioned to interpret your result in context.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
8. What should I do if my results are abnormal?
If your results fall outside the expected range, review them with a qualified healthcare provider. They can help determine whether additional evaluation or testing is appropriate based on your health history and symptoms. This test result alone does not provide a complete clinical picture.
9. How often should I get tested?
Testing frequency depends on your individual health situation and should be discussed with your healthcare provider. There is no standard repeat testing schedule for this test, and you should follow the guidance of your provider regarding whether retesting is appropriate.
