Measles immunity blood test in Chiswick
A blood test for measles IgG antibodies to check whether you are likely to be protected against measles, from vaccination or past infection, before travel, work in healthcare or planning a pregnancy.
What the test measures
Measles is a highly infectious viral illness that can cause serious complications, particularly in babies, pregnant women and people with weakened immunity. Protection comes from two doses of the MMR vaccine or from having had measles in the past.
This test measures measles IgG, the long-lasting antibody that indicates immunity. It is designed to answer the question "am I protected?" rather than to diagnose a current measles infection, which is confirmed through different tests arranged by your GP or the local health protection team.
The price includes the sample taken at our Chiswick clinic, analysis at the Randox accredited laboratory, a practitioner review of your result, and a GP feedback report on request.
Who it is for
- You are not sure whether you had both doses of the MMR vaccine.
- Your employer, university or placement asks for proof of measles immunity.
- You are planning a pregnancy and want to know your protection before you conceive.
- You are travelling to an area with measles outbreaks.
- You work with young children, in healthcare or in another setting where exposure is more likely.
Understanding your result
A positive IgG result suggests you have antibodies consistent with immunity. A negative result suggests you may not be protected, and the usual next step is to speak to your GP about MMR vaccination, which is free on the NHS for anyone who has missed doses. An equivocal result sits close to the cut-off and may be repeated or treated as not immune for practical purposes.
Antibody levels can fall over time even in people who remain protected, so your practitioner will read the result alongside your vaccination history.
Preparing for your test
No fasting or special preparation is needed. If you have received blood products or immunoglobulin in the last few months, please let us know, as this can affect antibody results. If you think you may have measles now, with fever, a rash and sore eyes, do not come to the clinic: phone your GP or NHS 111 first.
Measles immunity is often checked together with mumps and rubella immunity, which we also offer as separate tests. You can find these and all our other infection and immunity checks among every blood test and price in Chiswick.
Questions
How much is a measles immunity test in Chiswick?
The Measles Immunity test costs £99. It includes the blood sample at our Chiswick clinic, analysis at the Randox accredited laboratory, a practitioner review of your result, and a GP feedback report on request.
Can this test tell me if I have measles right now?
No. It looks for IgG antibodies that show immunity. A suspected current infection should be discussed with your GP or NHS 111 by phone before visiting any clinic.
What should I do if I am not immune?
Speak to your GP about the MMR vaccine. If you are pregnant, the vaccine is not given during pregnancy, so your GP or midwife will advise on timing.
Do I need fasting for a measles antibody test?
No. You can eat and drink as normal before your appointment.
