Why Get Tested?
To diagnose, as necessary, a current, recent, or past case of chickenpox or shingles; to demonstrate immunity to the varicella zoster virus (VZV) or the potential for reactivating a VZV infection prior to receiving immunosuppressive drugs
When to Get Tested?
When you have atypical and/or severe symptoms and your doctor wants to distinguish between a VZV infection and another cause; when a doctor wants to check whether or not you are immune to VZV; sometimes prior to an organ transplant or when a child, pregnant woman, or an immune-compromised person has been exposed to someone with chickenpox
A blood sample drawn from a vein in your arm for VZV antibody testing; to detect the virus itself, a sample of fluid from a blister (vesicle), blood, cerebrospinal fluid, or other body fluid or tissue
