The Varicella Zoster Virus (VZV) Antibody, IgG test is used to detect IgG antibodies in the blood against the varicella zoster virus, the virus responsible for chickenpox and shingles. The presence of IgG antibodies generally indicates past infection or immunity, either from previous exposure or vaccination.

This test is commonly performed to assess immune status, especially in individuals who are unsure of their vaccination history or previous infection. It is also useful in healthcare workers, pregnant women, and immunocompromised individuals where knowing immunity status is important.

A positive result typically suggests immunity to the virus, while a negative result may indicate susceptibility to infection. The test plays an important role in preventive healthcare and risk assessment.

The purpose of the Varicella Zoster Virus (VZV) Antibody, IgG test is to:

• Detect IgG antibodies against VZV
• Determine immunity to chickenpox and shingles
• Confirm past infection or vaccination status
• Assess susceptibility to VZV infection
• Support clinical evaluation in at-risk individuals
