Revisiting an old technique: rehydration of air-dried slides is a viable technique for Pap-stained fine needle aspiration slides for novel situations

Air-drying with delayed rehydration/alcohol fixation maintains diagnostic quality in settings for which traditional preparative techniques are not optimal, technical assistance is limited, and transport is problematic. Our series demonstrates that air-dried slides maintained high quality when processed up to 5 days postaspiration. We demonstrate a technique that improves pathology outreach by providing better quality diagnostic material with minimal additional personnel costs.
