Additional information This test is designed to measure IgG antibody. Positive results in neonates must be interpreted with caution, since maternal IgG is transferred passively from the mother to the fetus before birth. A definitive diagnosis requires viral isolation.

Samples collected very early in the course of an infection may not have detectable levels of IgG. In such cases, it is recommended that an IgM assay be performed.

Heterotypic antibodies exist between mumps and parainfluenza virus. Therefore, to confirm the clinical diagnosis of an atypical mumps infection, it is recommended that testing for parainfluenza be done simultaneously to rule out potential cross-reactivity.

Antibody response to vaccination is lower than that of a natural mumps infection.
