Endoscopy Diagnostic
Typical Use
Obtain cellular samples from bronchial mucosa for cytology and microbiology.
Description
A flexible, small diameter brush passed through the working channel of a bronchoscope to collect epithelial cells and secretions from bronchial lesions or airways for cytologic analysis, culture, and molecular testing; it complements forceps biopsy and lavage techniques to increase diagnostic yield for malignancy and infection. Proper technique involves targeted brushing under direct visualization, immediate specimen handling in appropriate transport media, and coordination with pathology and microbiology teams to optimize processing and interpretation. Brushes are single use or sterilizable depending on device design, and attention to contamination prevention and documentation of sampling sites enhances diagnostic accuracy. Bronchial brushing is valuable in evaluating endobronchial lesions, peripheral nodules with guidance, and suspected infectious etiologies.
