A rubella test helps doctors detect the rubella virus, also called German measles or 3-day measles. It is a blood test that finds antibodies to the virus, which can confirm whether or not a person has the infection. The test can also tell doctors if a person has been vaccinated to the virus, or that they've never been exposed to rubella at all. This test is often ordered for pregnant women, to be sure they have enough rubella antibodies to protect their baby from the virus. Other people may need the test if they have symptoms of the virus. Sometimes, the test is ordered for newborns, if their doctor suspects they've been exposed. The blood test results may be confirmed with tests of urine, or nose or throat swabs, or a nasal wash.
