The use of both chemical and biological indicators is essential in verifying the efficacy of Automated Endoscope Reprocessors (AERs). Chemical indicators are designed to respond to a specific process variable, typically by changing color, and they provide immediate, visual feedback that the required conditions for reprocessing have been met. However, while chemical indicators indicate that conditions for sterilization may have occurred, they do not confirm the actual sterility of the reprocessed instruments.

Biological indicators, on the other hand, contain viable microorganisms that are significantly more resistant to the sterilization process than the pathogens that might be present on contaminated instruments. The presence or absence of microbial growth after exposing biological indicators to the same sterilization process confirms whether the AER was effective. This dual-use of indicators—one providing immediate feedback and the other confirming sterility—ensures comprehensive monitoring of the reprocessing cycle's effectiveness, making it crucial for maintaining safety standards in healthcare settings.
