Mumps Virus IgG and IgM Antibodies |
 |
Mumps serological tests are usually performed for employee health screening. Orders for rubeola or mumps serology must indicate whether testing for IgM, IgG, or both antibodies is needed. If not specified, the laboratory will test for only IgG antibody. Employee health testing for immune status requires only IgG testing. IgM testing should be reserved for evaluation of atypical acute infections.
Reference range is < 1:5 for IgG and < 1:10 for IgM. The presence of IgM antibodies usually indicates acute infection. The presence of IgG generally indicates past exposure and immunity.
Specimen requirement is one SST tube of blood.
