||Swab of buccal area between cheek and gum near the upper molar area is preferred. A throat swab is also acceptable.
| Collection Device:
||Viral Transport Swab
Specimen Labeling - Test subject to CLIA regulations and requires 2 patient identifiers on specimen container and requisition forms
||Swab in viral transport media.
||Storage prior to shipment: Refrigerate at 2-8 °C
Shipping instructions, including specimen handling requirements during transport: Ship specimen Monday – Saturday, in biohazard bag with absorbent material at 2-8 °C. Transport by NPHL ground courier (NPHL brown shipper not required). If courier not available, contact Client Services at (866) 290-1406 to arrange pickup.

||Wood-tipped applicators, cotton-tipped swabs, calcium-alginate tipped swabs, charcoal swabs, gel swabs, anaerobic media.
| Specimen Stability:
||Specimen stable for 5 to 7 days refrigerated.
| Reference Interval:
||PCR negative for measles virus; not detected.
| Reportable Disease:
||A positive result is reportable within 7 days.
||A confirmed case is present if the specimen is PCR positive for mumps AND the patient has symptoms consistent with mumps. PCR has optimal sensitivity during the first three days after onset through day nine. PCR testing after nine days however is unlikely to be of benefit and is not generally recommended. PCR assays are not standardized across clinical laboratories and interpretation of PCR results must be done in conjunction with an evaluation of patient signs and symptoms and available epidemiological information. Also consider serological testing as an alternative method for diagnosis. (mumps IgM)
