Rubella Immunity Test in Colorado

The rubella immunity test is a blood test that checks whether you have protective antibodies against rubella, also called German measles. It is often ordered to confirm immunity before pregnancy or for people who may have been exposed to the virus.

What it measures

Rubella IgG antibody — Shows if you have antibodies that indicate past infection or vaccination, which usually means you are immune.
Rubella IgM antibody — Can suggest a recent infection, but it is not routinely used for immunity screening.
Antibody level — Some labs report a numerical level to help classify immunity as present or absent.

Who it is for

This test is commonly ordered for women planning pregnancy, pregnant women, and people who work in healthcare or childcare settings. It may also be used after a known or suspected exposure to rubella.

Preparation

No fasting or special preparation is needed for this test. You can eat and drink normally before your blood draw.

Results and what they mean

Results are usually reported as immune, not immune, or equivocal, based on the antibody level. A clinician interprets these results along with your health history and other factors. This information is general and not a substitute for medical advice.

Frequently asked questions

What does it mean if I am not immune?

It means your body does not show protective antibodies against rubella. Your clinician can discuss whether vaccination is right for you.

Do I need this test if I was vaccinated as a child?

Vaccination usually provides long-term immunity, but antibody levels can decline. A clinician may order the test to confirm your current status.

Is this test the same as a rubella infection test?

No. Immunity testing looks for past exposure or vaccination, while infection testing looks for recent or active infection.

How long does it take to get results?

Results are typically available within 1 to 3 business days after your blood sample is collected.
