Single slide assessment: A highly effective cytological rapid on-site evaluation technique for endobronchial and endoscopic ultrasound-guided fine needle aspiration.

No standardised, comprehensive approach to rapid on-site evaluation (ROSE) of cytology samples currently exists. Recent meta-analysis indicates variation in the effectiveness of ROSE, however, reviews commonly omit the details of how ROSE is conducted. This review demonstrates the clinical effectiveness of single slide assessment (SSA) for ROSE of cytology samples, providing a highly effective, standardised methodology, maximising cell yield and the diagnostic potential of samples obtained via endobronchial or endoscopic ultrasound.
