  1. What information must be documented for each endoscope reprocessing cycle?

    Answer: Scope ID, operator ID, date/time, disinfectant lot number, concentration test result, and cycle parameters

    Complete documentation creates a traceable record supporting quality assurance, infection control investigations, and regulatory compliance.

  2. How should a flexible endoscope be stored after successful reprocessing?

    Answer: Hung vertically in a ventilated, dedicated storage cabinet with all port caps removed

    Vertical hanging in a ventilated cabinet prevents moisture accumulation in channels and secondary contamination between clinical uses.

  3. Which US regulatory body is responsible for registering high-level disinfectants used in endoscope reprocessing?

    Answer: The Environmental Protection Agency (EPA)

    The EPA registers high-level disinfectants and sterilants used on medical devices in the United States under its pesticide regulatory authority.

  4. What does MRC stand for in the context of endoscope reprocessing chemicals?

    Answer: Minimum Recommended Concentration

    MRC (Minimum Recommended Concentration) is the lowest disinfectant concentration that must be maintained to reliably achieve high-level disinfection.

  5. What is the primary role of an Automated Endoscope Reprocessor (AER)?

    Answer: To perform automated high-level disinfection and rinsing after thorough manual cleaning

    AERs automate the HLD and rinsing phases but cannot replace the critical manual pre-cleaning step that must precede every cycle.

  6. Which endoscope accessory must always be single-use and never reprocessed for reuse?

    Answer: Any accessory labeled 'single-use only' (SUO) per FDA guidance

    FDA guidance requires that items labeled single-use only must not be reprocessed or reused, as safety and efficacy after reprocessing cannot be assured.

  7. What is the recommended approach to determining an endoscope's maximum hang time before re-reprocessing is required?

    Answer: Base hang time on facility-validated, evidence-based policy, often 5–7 days in a proper cabinet

    Hang time is facility- and evidence-based; most guidelines support 5–7 days in a compliant cabinet, but each facility must validate its own policy.
