Overview of the Varicella Zoster IgG Antibodies Test
The Varicella Zoster IgG Antibodies blood test measures IgG antibodies against Varicella Zoster Virus, providing evidence of previous chickenpox infection or immune response following vaccination.
The test assesses 1 specialist immunity biomarker: Varicella Zoster IgG (immunity).
Varicella Zoster Virus causes chickenpox during primary infection.
After the initial illness resolves, the virus remains latent in nerve tissue and can reactivate later in life as shingles.
VZV IgG usually develops following chickenpox or successful vaccination and can remain detectable long term.
Testing is therefore commonly used to establish whether somebody has evidence of previous immune exposure.
This can be particularly important for healthcare workers, people planning pregnancy and people preparing to start significant immunosuppressive treatment.
The test does not diagnose an active shingles episode.
A person with positive VZV IgG can still develop shingles because shingles represents reactivation of virus already present within the body.
Likewise, positive IgG does not mean somebody currently has chickenpox.
A negative result means the assay has not demonstrated measurable VZV IgG.
This can indicate susceptibility to primary chickenpox infection.
Vaccination history remains important because antibody testing and clinical protection are related but not perfectly interchangeable in every vaccinated person.
Where formal immunity evidence is required for work or training, the requesting organisation's criteria should be checked.
What Does the Varicella Zoster IgG Antibodies Test Check?
The test measures IgG antibodies associated with previous VZV infection or vaccination. This test measures 1 specialist biomarker.
Varicella Zoster IgG (immunity)
Measures VZV IgG antibodies, supporting assessment of previous chickenpox infection or vaccine-related immune response.
Who May Benefit From the Varicella Zoster IgG Antibodies Test?
VZV IgG testing can be useful when documented immune status is required.
People who are unsure whether they had chickenpox - IgG can provide evidence of previous infection.
Healthcare workers requiring Varicella immunity documentation - Occupational-health pathways commonly assess VZV immunity.
People planning pregnancy - Establishing susceptibility before pregnancy can inform vaccination decisions.
People preparing for immunosuppressive treatment - Knowing VZV immune status can help with infection-risk planning.
People with uncertain vaccination records - Antibody testing can provide additional information.
People with a previous equivocal VZV result - Repeat testing may clarify measurable immune status.
People requiring pre-vaccination assessment - IgG can help determine whether previous immunity is detectable.
Symptoms and Reasons to Consider the Varicella Zoster IgG Antibodies Test
This test is primarily used to assess immunity rather than symptoms.
Uncertain childhood chickenpox history - IgG can identify previous immune exposure.
Uncertain Varicella vaccination history - Laboratory testing can provide additional information.
Occupational-health immunity requirements - Healthcare environments commonly require evidence of immune status.
Pregnancy planning without clear chickenpox immunity - Susceptibility is preferable to identify before pregnancy.
Preparation for immune-suppressing treatment - VZV status can influence preventive planning.
VZV IgG does not diagnose active shingles or chickenpox.
A new vesicular rash requires clinical assessment and, when confirmation is required, PCR testing from an appropriate specimen.
How to Prepare
Varicella vaccination is a live vaccine and timing is particularly important around pregnancy and significant immunosuppression.
Vaccination decisions should follow appropriate medical guidance.

When Will I Receive My Results?
The current London Blood Tests page lists a customer-facing turnaround of approximately 4 days after laboratory receipt.
The underlying specialist laboratory assay itself is currently listed at approximately 1 day.
The LBT-facing four-day turnaround has therefore been retained for the product page.
Understanding Your Results
A positive result indicates measurable VZV IgG antibodies.
This usually reflects previous chickenpox infection or vaccination.
It provides evidence of immune exposure but does not mean shingles can never occur.
A negative result means measurable VZV IgG was not detected.
This can indicate susceptibility to primary Varicella infection.
An equivocal result falls close to the assay threshold and may require repeat testing.
The exact laboratory cut-off should be used rather than applying a universal threshold to all assays.
IgG does not establish whether a current rash is caused by VZV.
Why Book With London Blood Tests?
London Blood Tests provides private VZV IgG testing for immunity and occupational-health assessment.
Measures VZV-specific IgG - The test assesses previous immune exposure.
Useful when chickenpox history is uncertain - Laboratory testing can clarify whether antibodies are detectable.
Relevant to healthcare workers - VZV immunity is commonly assessed in occupational health.
Useful before pregnancy - Susceptibility can be identified before conception.
Relevant before immunosuppression - Immune status can help guide preventive planning.
Different from acute infection testing - IgG is used for previous exposure rather than active disease diagnosis.
Professional blood collection - Clinic and suitable home or hotel appointments are available.
Clear pricing - The Varicella Zoster IgG Antibodies test costs £88.
