Bronchoscopic culture is a laboratory exam to check a piece of tissue or fluid from the lungs for infection-causing organisms.
A sample of lung tissue is needed. For information on how that sample is obtained, see: Bronchoscopy
The sample is sent to a laboratory, and placed in a special dish (culture media) that allows bacteria, fungi, mycobacteria, or viruses to grow. The sample is placed under a microscope and examined daily for the presence of bacteria or other infection-causing organisms. Treatment is based on the results of the culture.
This article discusses the culture test. For information on preparing for the procedure to take the tissue sample, see: Bronchoscopy
A bronchoscopic culture is done to find infection in the lung that cannot be accurately detected by a sputum culture. The procedure may find evidence of infection, such as:
No organisms are seen on the culture.
Abnormal culture results usually indicate a respiratory infection. The infection may be caused by bacteria, viruses, parasites, mycobacteria, or fungi. The results of the culture will help determine the best treatment.
There are no risks involved with the laboratory culture. For risks involved with the bronchoscopy procedure, see: Bronchoscopy
