How is mumps diagnosed?
The doctor can usually diagnose mumps based on the swollen salivary glands. If the glands are not swollen and the doctor suspects mumps based on other symptoms, he or she will perform a virus culture. A culture is done by swabbing the inside of the cheek or throat. The swab collects mucus and cells and is sent to a lab to be tested for the mumps virus. It is important to remember than many viruses other than mumps can cause swelling of the salivary glands.
