Diagnosis of Respiratory infection
Identifying a specific etiologic agent, especially in the absence of pneumonia or serious disease, is not always clinically necessary. If indicated, the following methods of diagnosis can be used:
- Molecular methods are available to detect a number of respiratory viruses, including influenza virus, parainfluenza virus, adenovirus, human metapneumovirus, and respiratory syncytial virus, and for certain nonviral pathogens.
- Rapid tests are also available to detect some pathogens such as respiratory syncytial virus, influenza virus, L. pneumophila, and group A Streptococcus.
- Microbiologic culturing of sputum and blood, although insensitive, can help identify a causative respiratory pathogen.
- Special consideration should be given to diagnosing patients with suspected MERS (www.cdc.gov/coronavirus/mers/guidelines-clinical-specimens.html), H5N1 (www.cdc.gov/flu/avianflu/h5n1/testing.htm), or H7N9 (www.cdc.gov/flu/avianflu/h7n9/testing.htm).
