Rubella
Rubella (or “German measles”) is a contagious viral infection best known by its distinctive red rash. A rubella blood test detects antibodies that are made by the immune system to help kill the rubella virus. The presence of IgG antibodies may indicate a recent or past rubella infection, or indicate that a rubella vaccine (a measles, mumps, rubella vaccine) has been given and is providing adequate protection.
