Varicella Zoster Virus Antibodies, IgG

Varicella Zoster virus (VZV) is the virus that is responsible for chickenpox and shingles. VZV is a member of the herpes virus family. IgG is a type of antibody that is produced in response to disease which indicates lifelong immunity. When infected with VZV, IgG antibodies against VZV start to ride after several weeks of initial infection. At a point when the infection has been resolved, the level of IgG antibodies plateaus, providing the host with lifelong immunity to VZV. IgG, along with IgM are useful in determining whether there is active VZV disease or if there was previous exposure to the virus.

This test is performed in following conditions such as:

• Fever
• Tiredness
• Loss of appetite
• Headache
• Rash which is itchy or painful
• People at high risk of dying from VZV infection, such as transplant recipient or pregnant women
