Varicella Titer FAQ

What is a Varicella titer?

A Varicella titer is a blood test that checks for immunity to Varicella, also known as Chickenpox.

Why might I already be immune to Varicella?

People who have either been vaccinated with the Varicella vaccine or have had the chickenpox disease previously might be immune to varicella.

Who gets the Varicella titer?

A Varicella titer is typically ordered by healthcare workers for credentialing requirements (e.g. hospital, RepTrax, Vendormate) and students studying in healthcare programs. Additionally, some people get the Varicella titer to check immunity when they are going to be around a new baby or someone with a weakened immune system.

What type of Varicella titer results will I receive?

Our Varicella titer results report as the gold standard quantitative (i.e. a number) IgG titer test.

What does a positive Varicella titer result mean?

A positive Varicella titer result means that your immune system is producing an adequate level of antibodies to Varicella and that you do not have to be revaccinated with the Varicella vaccine.

What does a negative Varicella titer result mean?

If your Varicella titer result comes back negative, it means that your immune system is not producing an adequate level of Varicella antibodies to be considered adequately protected against the infection. In the case of a negative Varicella blood titer, it is typically recommended that you receive the Varicella vaccine.

What type of specimen will I submit?

This Varicella Titer is a blood test.

Do I need to fast to take this test?

Fasting is not necessary.

How long does it take to get test results?

It typically takes 4 business days or less.

More Varicella Titer Information

In most cases, people who need to demonstrate immunity through a Varicella titer will be studying or working in a healthcare setting. In this type of setting, there is an increased risk of being exposed to someone who has an active form of the varicella-zoster virus in their body (e.g. someone with the chickenpox). Schools and healthcare facilities are often required to make sure that anyone stepping into a healthcare setting has demonstrated Varicella immunity ahead of time through the Varicella titer in the event of an inadvertent exposure.

A Varicella vaccine is a weakened live version of the actual varicella-zoster virus (sometimes known as just VZV which is why the titer is sometimes known as a VZV titer) and is typically recommended after a negative Varicella titer result. The Varicella vaccine gives the recipient a very mild form of the chickenpox (usually without symptoms) and this serves as a way to expose the immune system to the Varicella infection. From this mild vaccine-induced illness, the immune system can develop and store a memory of the varicella-zoster virus and, if exposed in the future, can mount a powerful antibody response to protect the body.
