Submission and Collection Notes
Collect a buccal swab and urine for each patient suspected of having mumps. One General Test Requisition Form is sufficient for both specimens.
Buccal Swabs: massage the parotid gland area (the space between the cheek and teeth just below the ear) for about 30 seconds prior to the collection of the buccal secretions. The parotid duct (Stensen's duct) drains in this space near the upper rear molars. Put the swab into that space.
Refer to the Virus Respiratory Kit for collection of swab specimens.
CSF – testing may be performed in cases of aseptic meningitis.
