German measles, rubella antibody test, 3-day measles
This test measures the amount of rubella antibodies in your blood to see if you have immunity against the rubella virus.
Rubella is also called the German measles. It is a very contagious disease that's easily spread through coughing, sneezing, and spitting. In young children, rubella is usually a mild disease with symptoms that include sore throat and fever. Adults may have pink eye, headache, and discomfort up to 5 days before a rash appears.
It's important to know whether you have antibodies against rubella. This is especially true if you're pregnant or know that you have been exposed to the virus. Getting rubella when you're pregnant can be especially dangerous for your fetus. A rubella infection can cause miscarriage or a stillborn infant in the first 28 weeks of pregnancy. It can also cause many serious birth defects. These are more likely if the infection occurs in the first 12 weeks of pregnancy. Defects include heart defects, intellectual disability, liver problems, deafness, blood disorders, and cataracts. Infants may later have delayed motor skills, behavioral disorders, autism, immune disorders, thyroid problems, diabetes, and digestive disorders.
Once you've had rubella, you may get a natural immunity so you won't get it again. If you're not immune or never had rubella, you can get vaccinated.
If you are pregnant, you will have this test as part of your routine prenatal exams.
If you aren't immune to rubella, you can be vaccinated against the infection. But the shot is not recommended for women who are already pregnant. Women should not get pregnant for at least a month after having a rubella vaccine.
If you are pregnant, your healthcare provider may order a series of tests to look at your overall health. Your provider may also check for:
Blood type (A, B, AB, or O)
Rh factor (Rh positive or negative)
Iron and hemoglobin levels
Sexually transmitted diseases
Inherited diseases such as hypercholesterolemia, cystic fibrosis, sickle-cell anemia, thalassemia, and Tay-Sachs disease
Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your healthcare provider.
Normal results are positive, meaning that you have enough antibodies to give immunity against the rubella virus. Negative results mean that you don't have enough antibodies.
If you have rheumatoid arthritis or mononucleosis, you may have a false-positive result. If your immune system does not work the way it should, this test may give inaccurate results.
The test requires a blood sample, which is drawn through a needle from a vein in your arm.
When a blood sample is taken from a baby, it is usually drawn from the heel or, in a newborn, from the umbilical cord.
Taking a blood sample with a needle carries risks that include bleeding, infection, bruising, or feeling dizzy. When the needle pricks your arm, you may feel a slight stinging sensation or pain. Afterward, the site may be slightly sore.
If you've been treated for an immune system disorder or had a transfusion, you may get a false-positive result. People who have been exposed to parvovirus may also get false-positive results.
You don't need to prepare for this test.
