Certified Endoscope Reprocessor (CER) Practice Test 2025 – Complete Exam Prep

Testing the high-level disinfectant solution in an Automated Equipment Reprocessor (AER) before each use is critical to ensuring the effectiveness of the disinfection process. High-level disinfectants can degrade over time or become contaminated, which compromises their ability to effectively eliminate pathogens. By testing the solution prior to each use, healthcare personnel can confirm that the disinfectant is still within the required parameters for effective disinfection, ensuring patient safety and compliance with infection control standards.

Regularly verifying the concentration and efficacy of the disinfectant not only helps in maintaining the integrity of the equipment being processed but also aligns with best practices in sterilization and infection prevention protocols. This proactive approach minimizes the risk of infection, thereby safeguarding the health of patients and staff in the healthcare setting.

While daily, weekly, or per-procedure testing may seem reasonable, they do not provide the same level of immediate assurance as testing before each use. If any fluctuations in the disinfectant’s potency occur, waiting for longer intervals could lead to ineffective disinfection during procedures, potentially increasing the risk of healthcare-associated infections.
