Improper or ineffective cleaning of reusable endoscopes can undermine high-level disinfection and sterilization, exposing patients to extreme risk from poorly cleaned endoscopes. Rapid ATP testing quickly validates the effectiveness of detergents, equipment, and cleaning processes by detecting biological matter and bacteria left behind after ineffective cleaning. Flexible swabs for sampling internal channels and water tests for testing flushed water samples from elevator channels are both important components of a comprehensive cleaning validation program for scope reprocessing. Hygiena’s ATP Cleaning Verification system is an easy-to-use, affordable solution for verifying cleaning procedure effectiveness.
