I Would Like to Learn About:

How the Test is Performed

A procedure called bronchoscopy is used to get a sample (biopsy or brush) of lung tissue or fluid.

The sample is sent to a laboratory. There, it is placed in a special dish (culture). It is then watched to see if bacteria or other disease-causing germs grow. Treatment is based on the results of the culture.

How to Prepare for the Test

Follow your health care provider's instructions on how to prepare for bronchoscopy.

How the Test will Feel

Your provider will tell you what to expect during bronchoscopy.

Why the Test is Performed

A bronchoscopic culture is done to find infection in the lung that cannot be accurately detected by a sputum culture. The procedure may find the following things, such as:

Normal Results

No organisms are seen on the culture.

What Abnormal Results Mean

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.

Not all organisms found with bronchoscopic culture need to be treated. Your provider will tell you more about this if needed.

Risks

Your provider can discuss the risks of the bronchoscopy procedure with you.
