Bronchial Washings for Bacterial C/S (Aerobic) with Gram Stain

Specimen Required

BRONCHIAL WASHING

Fasting Required

Purpose of the Test

The Bronchial Washings for Bacterial C/S (Aerobic) with Gram Stain is performed to identify and diagnose bacterial infections in the lungs. The test helps in detecting the presence of bacteria in the bronchial washings collected from the lungs and determining the sensitivity of the bacteria to antibiotics.

When this test is required

The test is usually requested when an individual has symptoms of a respiratory infection and has not responded to initial treatment with antibiotics. It may also be requested when an individual is at high risk of developing a lung infection or has a weakened immune system.

What the Test Detects

The test involves examining the bronchial washings under a microscope to identify any bacteria present. The sample is then cultured on special media to allow the bacteria to grow. Once the bacteria have grown, they are tested against different antibiotics to determine which antibiotic(s) will be effective in treating the infection.

Preparation for the Test

Before the test, the individual may be asked to fast for a few hours. They may also be asked to stop taking certain medications that may interfere with the test results.

Sample Requirements

The sample required for this test is bronchial washings obtained through bronchoscopy, a procedure that involves passing a flexible tube with a camera through the mouth or nose into the lungs to collect the sample.

Additional Notes

Bronchoscopy, the procedure used to collect the sample for the test, may have some risks and complications, such as bleeding, infection, or a collapsed lung. It is important to discuss any concerns or questions with your healthcare provider before the procedure.
