What it measures
Rubella, also called German measles, is a viral infection. This test checks whether your body is protected against it, usually thanks to a childhood vaccine or a past infection.
Why it matters for women
Rubella during pregnancy, especially early on, can lead to miscarriage or to a baby born with hearing, eye or heart problems. Checking before you get pregnant gives you time to talk with your doctor if you’re not protected.
You might check it if…
- you’re planning a pregnancy or trying to conceive
- you’re not sure you had the rubella vaccine
- you’ve just found out you’re pregnant
- a school or employer asked for proof of immunity
What your result may mean
High Rubella immunity (IgG): what it may mean
High or positive rubella IgG may mean you are protected against rubella (German measles), through a past vaccine or a past infection. This result can be reassuring before pregnancy, because rubella early in pregnancy can lead to miscarriage or a baby born with hearing, eye or heart problems (congenital rubella syndrome). IgG can't tell a vaccine from a past infection, and it can't date when you were exposed. After a recent rash or known exposure, a clinician may order other rubella tests, such as IgM, to sort out the timing.
Low Rubella immunity (IgG): what it may mean
Low or negative rubella IgG may mean you are not protected (non-immune) against rubella, also called German measles. This can matter most in pregnancy, since catching rubella can put a baby at risk of congenital rubella syndrome, including hearing, eye and heart problems. Checking before you get pregnant can leave time to ask your clinician about vaccination, because the rubella vaccine can't be given during pregnancy. A result near the lab's cutoff may need repeating, and antibody levels can fade in the years after a vaccine.
