Abstrakt: Background: The need to monitor manual cleaning of high-risk endoscopes is recommended or more so required by the current endoscope reprocessing guidelines. The objective of this study was to establish the optimal extraction volume for colonoscopes and bronchoscopes and demonstrate the extraction efficacy for the ChannelCheck™ rapid test.
Methods: The test soil utilized as a positive control was ATS2015 containing 20% defibrinated bovine blood. The extraction from the instrument channel of a colonoscope and bronchoscope was evaluated to establish the optimal extraction volume and the extraction efficacy for protein, carbohydrate and haemoglobin.
Results: Of the extraction volumes tested, 10 mL was optimal for both colonoscopes and bronchoscopes. The extraction efficacy was 91% for carbohydrate, 83.7% for haemoglobin and 82.4% for protein.
Conclusions: The limit of detection for these analytes by the ChannelCheck rapid test meet or exceed the established levels that correlate with adequate manual cleaning of flexible endoscopes.
