| Test: | Mumps Virus RNA Detection |
| Synonym: | Mumps Virus by RT-PCR |
| Method: | Reverse Transcriptase (RT) - RNA Amplification |
| Availability: | Pre-Approval Needed from Local or State Health Department. Approval must be sent to nphl@unmc.edu or can notify NPHL by phone at (402) 559-9444. NPHL Special Microbiology Requisition and Vaccine Preventable Disease forms required. Include vaccination history, age, date of onset, and date of sample collection. Results available 48 hours after receipt of specimen in reference laboratory. |
| Specimen: | 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 |
| Volume: | Swab in viral transport media. |
| Storage/Transport: | Storage prior to shipment: Refrigerate at 2-8 °C |
| Unacceptable: | 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. |
| Comments: | 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) Test Performed at CDC Reference Laboratory |
