Rubella Test

German Measles (Rubella) Test

Results

A rubella blood test detects antibodies that are made by the immune system to help kill the rubella virus. The results of a rubella test are given in titres. Titres measure how much the blood sample can be diluted before the antibodies can no longer be detected.

A positive test result means that antibodies against rubella were found in your blood. This may mean you have a current or recent rubella infection, or it may show that you have immunity against rubella. Immunity could have been received through either vaccination for rubella or a past rubella infection.

Some babies born with birth defects may be tested for congenital rubella.
