The measles immunity test is a blood test that checks whether you have antibodies against the measles virus. It is often ordered to confirm immunity from past infection or vaccination, or to see if you need a booster.
What it measures
- Measles IgG Antibodies — Shows if you have protective antibodies from past infection or vaccination.
- Measles IgM Antibodies — May be included to detect a recent or current infection.
- Antibody Level (Titer) — Measures the amount of antibodies, helping assess your level of protection.
Who it is for
A clinician may order this test for people without vaccination records, those at higher risk of exposure (such as healthcare workers or travelers), or before pregnancy.
Preparation
No fasting or special preparation is needed. Tell your clinician about any recent vaccinations or immune treatments, as they can affect results.
Results and what they mean
Results are usually reported as positive (immune), negative (not immune), or equivocal (uncertain). Your clinician interprets these in the context of your health and vaccination history. This is general information, not medical advice; discuss your results with a healthcare professional.

Frequently asked questions
Do I need this test if I was vaccinated as a child?
Not always. Most people vaccinated with two doses are considered immune, but a test can confirm if there is any doubt.
What does a negative result mean?
It means no protective antibodies were detected. Your clinician may recommend vaccination, depending on your situation.
Can I get measles even if the test is positive?
A positive result generally indicates protection, but no test is perfect. Your clinician can explain your specific risk.
How long does it take to get results?
Results are typically available within 1–3 business days after your blood sample is collected.
