Bronchial brush or wash culture for fungal organisms

Why This Test Is Done

Your doctor may order this test if you have symptoms like persistent cough, chest pain, or fever that could indicate a fungal infection. It’s particularly useful for people with conditions that weaken the immune system, such as HIV/AIDS, cancer, or long-term steroid use, or those who have had recent lung procedures.

What to Expect Before the Test

You may need to prepare by avoiding certain medications (like antifungals) or fasting, depending on the procedure. For a bronchial wash, you might receive a sedative to stay comfortable. For a brush, you may breathe into a tube inserted through your nose or mouth.

How the Test Is Performed

A healthcare provider will use a bronchoscope—a thin, lighted tube—to reach your bronchi. Secretions or cells are collected either by washing the airway with saline or by brushing the lining. The sample is then sent to the lab for fungal growth.

What the Results Mean

Positive results show the presence of fungal organisms, confirming a fungal infection. Negative results mean no fungi were found in the sample, but other causes of symptoms should still be investigated. Follow-up tests or treatments may be needed based on the results.
