Waste not, want not: diagnostic material found in suction syringe aspirate during endobronchial ultrasound guided transbronchial needle aspiration.

Background: Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a frequently performed procedure. Suction is utilized during this procedure and may occasionally result in the collection of aspirated material, the diagnostic utility of which is uncertain. This study aims to determine the contents of the suction syringe aspirate and its diagnostic value.
