Mumps IgG Antibodies; Mumps IgM Antibodies
The presence of mumps specific-IgM or -IgG antibodies would suggest previous immunization or exposure to the mumps virus. In non-immunized individuals, the detection of mumps specific-IgM antibodies would suggest an acute infection or when paired acute and convalescent specimens (two to three weeks apart) are evaluated with a 4-fold or greater rise in mumps specific-IgG antibodies, an acute infection is suggested. An acute infection should be corroborated with clinical presentation. Please note that results from a single IgM assay should not be used as the sole determinate of an acute infection, as IgM test results may yield false positive results and low levels of IgM antibody can persist for more than 12 months post infection. If an acute infection is indicated, submit an additional specimen in two or more weeks for IgM and IgG testing.
