Chickenpox IgM Antibody Test (VZV)
Confirm recent chickenpox or shingles exposure with confidence.
The Chickenpox IgM Antibody Test (VZV) is a blood test used to detect recent or acute infection with the varicella zoster virus (VZV), the virus responsible for chickenpox and shingles. It is most useful when a patient presents with symptoms suggestive of chickenpox or shingles and the clinician needs confirmation, or when assessing exposure in individuals who are uncertain of their immune status. This test is for anyone who needs clarity on whether they have had a recent VZV infection, including those with a rash illness, pregnant women, and individuals in occupational health settings where VZV immunity is relevant.
What it screens for
- Varicella Zoster Virus (VZV) IgM: The presence of IgM antibodies indicates a recent or current infection with VZV. This marker helps distinguish acute infection from past exposure or vaccination.
Why it matters
Identifying a recent VZV infection allows for appropriate clinical management, including monitoring for complications and advising on infection control measures. For pregnant women and immunocompromised individuals, early detection is particularly important to guide care and reduce the risk of severe outcomes. In occupational health, confirming recent infection can inform decisions about fitness for work and exposure risk.
