VZV Antibody Blood Test (IgM)

Understanding  varicella-zoster virus (VZV) antibody testing

This blood test detects antibodies that your immune system has produced in response to the VZV virus. The varicella-zoster virus is highly contagious and can cause either chickenpox or shingles. Typically, the first exposure to this virus results in chickenpox.

This test is commonly used to determine immunity to the varicella-zoster virus (VZV), particularly in individuals who may have been exposed to the infection and are considered high-risk. This test may also be carried out prior to vaccination or in cases where patients are experiencing atypical or severe symptoms of chickenpox or shingles.

Can I check my chicken pox immunity?

Yes, you can. A specific blood test, known as the whole infected cell ELISA test, can detect antibodies produced by your body after exposure to the varicella-zoster virus. This test uses a blood sample to confirm seroconversion (the development of antibodies) after infection.

How can I tell if I have chickenpox immunity?

If you are unsure whether you’ve ever had chickenpox, an immunity test can provide answers. This test checks for antibodies to the virus that causes chickenpox. If antibodies are present, this means you are protected or immune to the virus.

Will the varicella-zoster virus immunity last, and for how long?

When live vaccines are administered, they often provide long-term immunity. Research indicates that antibodies developed following VZV vaccination can persist for 10 to 20 years.

How long do chickenpox antibodies stay detectable?

• IgM Antibodies: These antibodies typically appear within five days from the onset of the chickenpox rash. Their levels peak around two to three weeks after infection and then decline rapidly, becoming undetectable approximately 12 months later.
• IgG Antibodies: These antibodies also diminish over time but can remain detectable for several years, providing a positive result on immunity tests.
