RT-PCR |
| Test Includes |
Norovirus 1 by RT-PCR; Norovirus 2 by RT-PCR. |
| Reference Ranges |
Norovirus 1 by RT-PCR Not detected
Norovirus 2 by RT-PCR Not detected
A result of not detected does not rule out the presence
of PCR inhibitors in the patient specimen or norovirus nucleic
acid in concentrations below the level of detection of the
assay. This test is performed pursuant to an agreement with
Roche Molecular Systems, Inc. |
