The Varicella Zoster Virus (VZV) Titer is a blood test that checks if you are immune to Varicella Zoster Virus, also known as Chickenpox and Shingles. It measures your antibody levels to get a sense for whether your immune system has the capability to respond to an infection with one of these diseases.
The varicella titer test (chicken pox test) is recommended for anyone who may require a chickenpox vaccination and needs to verify their immunity status. Chickenpox vaccinations are necessary for teachers, childcare workers, healthcare workers, students, military personnel, international travelers, inmates and staff of correctional institutions, and adults living with children. Women who are planning to become pregnant should receive a varicella titer test.
