Rubella Antibodies, IgM
•German Measles Specific IgM
For the in vitro detection of IgM antibodies specific for rubella. IgM antibodies are associated with acute viral infections. IgM detection is useful in the following situations: evidence of infection can be obtained from only one acute phase specimen if the IgM results are positive; the IgM test can also be used to differentiate between primary infection and re-exposure. Rubella-specific IgM is found in virtually all infected patients by three weeks postdevelopment of a rash. Rubella-specific IgM is also found in 80% of postvaccination patients by three weeks. Congenitally infected infants will show an IgM response at 2 to 12 weeks postnatally
