Influenza prevalence fluctuates seasonally with the onset of “flu season” typically beginning its upswing in the month of December. It is important for providers to have an awareness of influenza prevalence (in addition to other respiratory viruses) to help guide when influenza testing should be pursued.

Inform: RSV Testing – Age Restrictions
Respiratory syncytial virus (RSV) primarily infects pediatric patients, but occasionally infects adults and may be of particular concern for the elderly and immunocompromised. Corewell Health Laboratories offers two tests for RSV. A rapid antigen test may be used to confirm RSV diagnosis in pediatric patients. This test is not approved by the FDA for testing adult patients, so tests will be cancelled if ordered on an off-label age group. There are no age restrictions for RSV testing by way of a molecular panel that also includes COVID and influenza as viruses with overlapping symptoms.
| Test name | Epic Test ID | Methodology | Specimen | Age restriction |
| RSV Rapid | LAB495 | Antigen | Nasopharyngeal (NP) swab | Approved for patients 0 – 18 years of age |
| COVID, Influenza, RSV PCR | LAB1230746 | Molecular/PCR | Nasopharyngeal (NP) swab | No age restriction |

Outpatient Respiratory Viral Testing
Spectrum Health Lab has noticed an increase in outpatient orders for Respiratory Pathogens by Film Array [LAB3359]. This may be due to a shortage of supplies for some Point of Care (POC) testing platforms. Film Array is typically used for emergency and high acuity patients and therefore has a high cost that may not be covered by most patients’ insurance. To lesson out of pocket costs for your patients, please order the below for RSV, COVID, or Flu testing.
