Tracheal Aspirate for AFB Stain

The Tracheal Aspirate for AFB Stain is a diagnostic test that involves collecting a sample of mucus or fluid from the trachea, which is the windpipe, to check for the presence of acid-fast bacilli (AFB), the bacteria responsible for tuberculosis. This procedure is typically performed using a thin tube inserted through the mouth or nose into the trachea, allowing for direct sampling of respiratory secretions. The sample is then stained and examined under a microscope to determine if AFB are present, helping to diagnose or rule out a tuberculosis infection.
