The Varicella Zoster Virus, also known as VZV, is the causative agent of chickenpox and shingles. After the initial infection, the virus remains inactive in nerve tissue and can reactivate later in life, leading to shingles.
Testing for VZV can be useful for people who are unsure if they have had chickenpox in the past, or for the diagnosis of a current infection with the virus. It is also relevant for pregnant women, immunocompromised patients, and prior to receiving certain vaccines.
The presence of antibodies against VZV in the blood can indicate a current or prior infection. An active VZV infection can be confirmed by detecting the virus itself or its DNA in blood or skin lesions.
A high level of VZV antibodies suggests recent exposure to the virus or a recent or active infection. In people with symptoms, this may indicate an active VZV infection.
A low level of VZV antibodies may mean that a person is not immune to the virus, which means they are susceptible to infection with chickenpox or shingles.
