Nasopharyngeal culture is a sample of secretions from the uppermost part of the throat, behind the nose, to detect organisms that can cause disease.
Culture - nasopharyngeal; Swab for respiratory viruses; Swab for Staph carriage
You will be asked to cough before the test begins and then tilt your head back. A sterile cotton-tipped swab is gently passed through the nostril and into the nasopharynx, the part of the pharynx that covers the roof of the mouth. The swab is quickly rotated and then removed.
There is no special preparation necessary.
You may experience slight discomfort and may gag.
The test identifies viruses and bacteria that cause upper-respiratory tract symptoms. Nasopharyngeal cultures are useful in identifying respiratory viruses, and bacteria such as:
- Bordetella pertussis
- Neisseria meningitidis
- Staphylococcus aureus
The culture may be used to help determine which antibiotic therapy is appropriate.
The presence of organisms commonly found in the nasopharynx is normal.
The presence of any disease-causing virus, bacteria, or fungus means these organisms may be involved in your infection.
There are no risks.
