Unsure of your immunity status? Test for chickenpox immunity.
The Chickenpox Immunity Test can help determine whether you have immunity to Varicella-Zoster Virus (VZV) from a past infection or vaccination. The test measures VZV IgG antibodies, which are produced by the immune system after exposure to the virus or the chickenpox vaccine. Results are reported as either reactive or non-reactive only. A reactive result means antibodies were detected and may indicate immunity to chickenpox. A non-reactive result means antibodies were not detected. This test does not provide a numerical antibody level. If you need proof of immunity for work, school, or another requirement, check whether a reactive/non-reactive result meets the documentation requirements.
Chickenpox is a highly contagious disease caused by the varicella-zoster virus. Symptoms include itchy, blister-like rashes that can spread across your body. Although vaccination has greatly reduced the number of cases, knowing your immunity status may still be important for school, work, healthcare requirements, pregnancy planning, travel, or personal peace of mind. If you're unsure whether you've had chickenpox or received the vaccine, this test can provide clarity about your immunity status.
Note: This test is not intended to diagnose an active chickenpox infection. If you are experiencing symptoms of chickenpox or believe you have been exposed to the virus, contact a healthcare provider for appropriate evaluation and next steps.

These antibodies are produced by the immune system after chickenpox infection or vaccination. This test evaluates whether VZV IgG antibodies are detected and reports results as reactive or non-reactive. Results do not include a numerical antibody level.
Proof of immunity is commonly a requirement for work and school.
This blood test can determine your immunity to VZV or Chickenpox from a past infection or vaccination and the results provided can be part of your immunization record.
Not everyone can receive the chickenpox vaccine due to health conditions.
Chickenpox can be serious or even life-threatening, especially during pregnancy, in babies, adolescents, adults, and people with weakened immune systems.² Making sure you're immune can help avoid spreading chickenpox and protect those who are most vulnerable.
