- Bronchoalveolar lavage (BAL) is a procedure where a tube is passed through the mouth or
nose into the lungs. Fluid is squirted through the tube into a part of the lung and then
collected for examination. It is used to detect respiratory viruses. BAL is a relatively
invasive procedure, and researchers want to test the accuracy of other procedures that do not
involve collecting fluid from the lungs. The nasopharynx is the area of the upper throat that
lies behind the nose. Researchers want to see if a swab taken from this area is as accurate
as a BAL sample.
- To see if a nasopharynx swab can be used to detect respiratory viruses as well as BAL
- Individuals at least 12 years of age who will have a bronchoscopy to collect a BAL sample
to test for respiratory viruses.
- Participants will be screened with a physical exam and medical history.
- Participants will have a BAL sample collected.
- Participants will then have a nasopharynx swab. The swab will be inserted into the nose,
left in place for up to 10 seconds, and then removed
