This test measures the level of IgG antibodies to rubella (German measles) in your blood which will tell you whether you have acquired immunity to the rubella virus. A positive result means that you are immune to rubella and a negative result means that you do not have immunity.
Rubella is a virus which is usually caught through coughs and sneezes. Common symptoms include mild flu-like symptoms and a rash that starts behind the ears and spreads to the upper body. However, many people don’t experience any symptoms at all. Although in most people rubella is harmless it can harm an unborn baby, especially if the mother contracts rubella in the early weeks of pregnancy.
Immunity to rubella can be acquired through vaccination or having recovered from a previous infection. Young people who missed their MMR (measles, mumps rubella) vaccination in infancy may not be protected against rubella.
Health care workers may be required to prove their rubella immunity to their employer.
