The Rubella IgG Titer Test measures antibodies against rubella (German measles) in your blood. It is used to check whether you are immune, either from past infection or vaccination, and is often ordered before or during pregnancy.
What it measures
- Rubella IgG Antibodies — The main marker; a positive result generally means you have protection against rubella.
- Rubella IgM Antibodies — Sometimes included to detect a recent or active infection, but not part of this test.
- Immune Status — A qualitative interpretation (immune or not immune) based on the IgG level.
- Antibody Level (if quantitative) — A numeric value in IU/mL that helps assess the strength of immunity.
Who it is for
A clinician typically orders this test for women who are pregnant or planning pregnancy, and for people who need to document immunity for school, work, or travel.
Preparation
No fasting or special preparation is needed. A blood sample can be taken at any time of day.
Results and what they mean
Results are usually reported as positive (immune), negative (not immune), or equivocal (uncertain). Your clinician will interpret the result in the context of your health history. This is general information, not medical advice; discuss your results with a qualified healthcare provider.

Vaccination usually provides long-lasting immunity, but antibody levels can decline. Your clinician may order the test to confirm your current status.
What does a negative result mean?
A negative result suggests you may not be immune to rubella. Your clinician can discuss whether vaccination or other steps are appropriate.
Is this test done during pregnancy?
Yes, it is commonly part of routine prenatal screening to check for immunity early in pregnancy.
How long does it take to get results?
Results are typically available within 1 to 3 business days after the sample is received by the lab.
