The Measles, Mumps, Rubella Immunity blood test measures IgG antibodies against the measles virus, mumps virus, and rubella virus. These antibodies indicate whether your immune system has developed protection following MMR vaccination or previous natural infection.
This test is widely used to confirm immunity in adults with uncertain vaccination history, healthcare workers, students, travellers, and individuals planning pregnancy. It does not diagnose active infection; instead, it confirms whether long-term immune protection is present.
Because immunity can vary between individuals and may decline over time, antibody testing provides a reliable way to determine whether revaccination or booster doses are required.
This test is recommended when confirmation of MMR immunity is required for medical, occupational, or personal reasons.
Testing may be appropriate if you:
We offer two convenient UK-wide testing options:
Clinic-based blood testing
Home or hotel blood collection (+£60)
Both options provide the same laboratory accuracy and clinical reliability.
Non-immune or low antibody levels
Low or absent antibodies indicate no confirmed immunity to one or more of the viruses.
Typical UK interpretation:
MMR vaccination or booster doses may be recommended.
Immune / protective antibody levels
Protective IgG antibodies indicate established immunity to measles, mumps, and/or rubella.
Typical UK interpretation:
No further action is usually required.
Mixed immunity results
Some individuals may be immune to one or two viruses but not all three.
Typical UK interpretation:
Clinical guidance may recommend vaccination depending on circumstances.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
