Details about Measles Antibodies (IgG) Immunity
Understanding the Measles Antibodies (IgG) Immunity blood test
The Measles Antibodies (IgG) Immunity blood test detects IgG antibodies produced by the immune system in response to the measles virus. These antibodies provide long-term protection and remain detectable after successful vaccination or natural infection.
This test does not diagnose active measles infection. Instead, it confirms whether immune memory is present, making it particularly useful for adults with uncertain vaccination history, healthcare workers, travellers, and individuals planning pregnancy.
Measles is a highly contagious viral infection, and confirming immunity is essential for both personal protection and public health compliance.
When a Measles Antibodies (IgG) Immunity test is recommended
This test is recommended whenever proof of measles immunity is required or when vaccination status is uncertain.
Testing may be appropriate if you:
- Are unsure whether you received the measles or MMR vaccine
- Need immunity confirmation for work or education
- Are a healthcare or childcare worker
- Are planning pregnancy or fertility treatment
- Are travelling to areas with measles outbreaks
- Were vaccinated many years ago and want reassurance
- Are immunocompromised or have reduced immune response
- Need evidence of immunity for official documentation

Follow these guidelines for accurate results
Sample Timing
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 & Hydration
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.
Medications & Supplements
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.
Hormones & Menstrual Cycle
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.
