Laboratory Findings
Testing for a specific viral cause (e.g. RSV by nasopharyngeal aspirate) is common, but has little effect on management. Identification of RSV-positive patients can be helpful for:
- Disease surveillance
- Grouping ("cohorting") patients together in hospital wards as to prevent cross infection.
- Predicting whether the disease course has peaked yet
- Reducing the need for other diagnostic procedures (by providing confidence that a cause has been identified)
Tests include:
- Blood gases
- Nasal fluid cultures (to determine which virus is present)
