Overview | |
|---|---|
| Department | Microbiology – Molecular |
| Test Code | TCOV |
| Synonyms | COVID-19
SARS-CoV-2 Novel Coronavirus 2019-nCov |
| Base Lab Availability | Monday - Friday, Testing routinely available out of hours |
| Hawera Lab Availability | Monday - Friday, 8am to 4 30pm |
| Turnaround Time | 2 – 24 hours from receipt
Results may be delayed out of routine business hours. Urgent requests will be prioritised |
| Stability – Add test | Add-ons can be made if an appropriate sample has already been received for other PCR testing within one week of specimen collection. |
Specimen Requirements | |
| Specimen | Swab |
| Preferred | Nasopharyngeal swab in VTM (Viral transport medium) |
| Acceptable | |
| Unacceptable | |
| Specimen Transportation | ASAP to Laboratory |
| Paediatric Requirements | Paediatric nasopharyngeal swab in VTM (Viral transport medium) |
Aliquot Requirements | |
| Sample | |
| Preferred Volume | |
| Minimum Volume | |
| Aliquot Transportation | If there is a delay in getting sample to the laboratory, please store sample chilled (2 - 8 degrees Celsius) |
Clinical Information | |
| Reference Intervals | Results will be reported as Novel Coronavirus RNA PCR DETECTED or NOT Detected.
Ct values are available on request. Specimens that fail for technical reasons will be tested by another platform or a repeat sample requested, this will mean a delay in results |
| Test Method | Real-time RT-PCR test on the GeneXpert analyser for the qualitative detection of nucleic acid from the SARS-CoV-2 virus.
Note if a “QUAD” swab is requested then Influenza A + B, RSV, and SARS-CoV-2 are tested. |
| Advanced Notice | Not required |
| Patient Preparation | To minimise inhibition in the assay, please ensure the patients blow their nose prior to taking a nasopharyngeal swab. |
Comments | |
| Influenza A/B and RSV, Full Respiratory Multiplex and Bordetella pertussis PCR may be carried out on the same nasopharyngeal swab.
Please note: Testing of the full respiratory multiplex assay does not have the same turnaround time as the Influenza A/B, RSV test as the sample is forwarded to a reference laboratory. | |
