VARICELLA ZOSTER - CHICKENPOX IMMUNITY BLOOD TEST

Varicella Zoster, also referred to as the virus responsible for chickenpox and shingles, is a type of herpes virus. In its abbreviated form it is referred to as VZV, this is how it appears on a lot of request forms.

The Varicella Zoster virus (sometimes just caused VZV) is the virus that is responsible for chicken pox and shingles. The majority of people in the UK will be infected with VZV at some point in childhood and this will confer immunity to them. The virus can then lay dormant in the body’s nervous system and may reactivate later in life as the painful, blistering rash known as shingles.

When someone is initially infected with VZV, the body mounts an immune response which includes the production of the immunoglobulin IgM. A few weeks later, the body produces the immunoglobulin IgG which persists in the blood as part of the immune system’s ‘memory’ of the virus, whilst IgM levels fall.

A positive IgG and a negative IgM therefore demonstrates previous infection (or vaccination) and the presence of immunity.

REPORTING OF LEVELS

The levels are reported as POSITIVE, EQUIVOCAL or NEGATIVE. 

POSITIVE: > 150 = IMMUNE. No upper limit. Antibodies present against the pathogen. There has been contact with the antigen (pathogen resp. vaccine).

NEGATIVE: The sample contains no antibodies against the pathogen. A previous contact with the antigen (pathogen resp. vaccine) is unlikely.

EQUIVOCAL: Antibodies against the pathogen could not be detected clearly. You will have to repeat the test with a fresh sample in 2-4 weeks. If it is equivocal again, the sample is judged as negative.

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

FREQUENTLY ASKED QUESTIONS

Here are some of the most frequently asked questions about the Varicella Zoster - Chickenpox Immunity Blood Test.

Do I need this test if I’ve had chickenpox or the vaccine?

If you have documented evidence of prior chickenpox or full vaccination, testing is usually not necessary.

However, if you’re unsure of your history, especially if you're in a high-risk group such as healthcare workers or pregnant women, testing can confirm your immune status.

Is fasting required before the VZV blood test?

No, fasting is not required. The test simply involves a standard blood draw and can be performed at any time of day.

WHY HAVE THE TEST?

Hi, I am Nader Eldarf, I am a Biomedical Scientist in our laboratory and here is why it's important to take this test.

  1. WHY HAVE THE VARICELLA ZOSTER - CHICKENPOX IMMUNITY BLOOD TEST?

    The Varicella Zoster Virus (VZV) blood test is important because it helps you determine whether you have immunity to the virus that causes chickenpox and shingles.

    Knowing your immune status is especially crucial if you’re pregnant, immunocompromised, or work in environments where exposure risk is high, such as healthcare or childcare settings.

IS THIS TEST RIGHT FOR YOU?

Hi, I am Sandeep Patel, I am the Laboratory Director at One Day Tests. Here are the symptoms that you may wish to address with this test.

  1. IS THE VARICELLA ZOSTER - CHICKENPOX IMMUNITY BLOOD TEST RIGHT FOR YOU?

    The Varicella Zoster Virus (VZV) blood test may be right for you if you are unsure whether you’ve had chickenpox or been vaccinated, especially if you are in a high-risk group.

    This includes pregnant women, healthcare or childcare workers, people with weakened immune systems, or those preparing for immunosuppressive treatments.

    The test can confirm whether you have immunity to VZV or are at risk of infection.
