Reference Values

Reference Ranges:  Negative

Result Interpretation: The Analyzer automatically calculates mumps virus IgG antibody concentrations expressed as arbitrary units (AU/mL) and grades the results.  Diagnosis of infectious diseases should not be established on the basis of a single test result, but should be determined in conjunction with previous infection history, clinical findings and other diagnostic procedures as well as in association with medical judgment.

 

AU/mL Value

Results

Interpretation

< 9.0 AU/mL

Negative

Absence of detectable mumps virus IgG antibodies.  A negative result generally indicates that the patient has not been infected and is susceptible to mumps.  If the subject has no history of mumps, has not been previously vaccinated and exposure to mumps virus is suspected despite a negative finding, a second sample should be collected and tested no less than one to two weeks later.

≥ 9.0 AU/mL

and

< 11.0 AU/mL

Equivocal

Equivocal samples should be retested.  If the result remains equivocal and repeat testing, a second sample should be collected no less than one to two weeks later.

≥ 11.0 AU/mL

Positive

Presence of detectable mumps virus IgG antibodies.  A positive result generally indicates past exposure to mumps virus or previous vaccination.
