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 test?
This test measures IgG antibodies to Varicella Zoster Virus (VZV) to help a healthcare provider evaluate your history of exposure through past infection or vaccination. It is not a panel, does not measure other antibody types, and does not diagnose an active infection or confirm immunity on its own.
2. When might I consider ordering this test?
You may consider this test if you want to review your VZV antibody status, are unsure of your chickenpox or vaccination history, or are discussing VZV with a healthcare provider. It may also be relevant for people with weakened immune systems or pregnant individuals discussing their VZV status with their provider.
3. Does this test measure other antibody types?
No. This test measures VZV IgG antibodies only. It does not measure IgA, IgM, IgE, IgD, 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.
4. Do I need to fast or prepare before this test?
No special preparation is required.
5. How quickly will I get results?
Results are typically available in 2–3 business days. Weather, holidays, or laboratory delays may extend this timeframe.
6. 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 considers. A positive result does not automatically confirm an active infection and may reflect past infection or vaccination. A negative result does not necessarily rule out prior exposure.
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.
7. What should I do if my result is outside the expected range?
Review your result with a qualified healthcare provider. They can determine whether additional evaluation or testing is appropriate based on your health history and symptoms. This result alone does not provide a complete clinical picture.
8. How often should I get tested?
There is no standard repeat-testing schedule. Discuss whether and when retesting is appropriate with your healthcare provider.
