- Viral Antibody: Mumps Virus IgM
If acute Mumps virus infection is suspected, it is recommended to communicate with your state health laboratory or the CDC to evaluate your patient. Michigan clients may contact the Michigan Department of Health & Human Services (MDHHS) Bureau of Epidemiology at 517-335-8165 for assistance in evaluation of your patient. Michigan Medicine physicians can contact Infection Prevention and Epidemiology at 734-936-6355 or page 30032.
As the prevalence of mumps is low, routine serology testing for anti-mumps IgM antibodies may yield false positive results. Patients having an illness with acute onset of unilateral or bilateral tender, self-limited, swelling of the parotid or other salivary gland, lasting 2 or more days, and without other apparent cause should be discussed with public health officials. Appropriate testing in this situation would consist of Mumps PCR, performed on oral/buccal swabs submitted in viral transport media. Testing is performed only with prior approval by the Michigan Department of Health and Human Services. Pre-approval arrangements must be made through Infection Prevention and Epidemiology at 734-936-6355 or page 30032
