Rubella Virus - IgM

What is a rubella antibody IgM test?
A rubella virus IgM test is done to determine if you have sufficient rubella antibodies to protect you from the rubella virus, to verify a past infection, or to detect a recent infection. Rubella is a viral infection that lasts about 2–3 days, hence it is also known as a 3-day measles test. The rubella IgM is the first type of antibody that appears in the blood after exposure to the virus.
