Point-of-use pre-cleaning comes first, followed by leak testing, then full manual cleaning with detergent.

What is the significance of 'biofilm' in endoscope reprocessing?

Answer: A community of microorganisms encased in a matrix that resists standard disinfection

Biofilm is a microbial community that adheres to surfaces and is highly resistant to disinfectants, making thorough mechanical cleaning critical.

When should the detergent solution used for manual cleaning be changed during a reprocessing session?

Answer: According to manufacturer IFU, or when visibly soiled/turbid

Detergent solutions become contaminated with organic matter and lose efficacy; they must be changed per manufacturer instructions or when visibly soiled.

Answer: Gloves, gown, mask, and eye protection

Manual cleaning involves exposure to blood, body fluids, and aerosolized biocontaminants, requiring full PPE including eye protection.

What action should be taken if the endoscope fails the leak test?

Answer: Remove the scope from service and send for repair before further use

A scope that fails the leak test must be removed from service immediately and sent for repair to prevent patient harm and further instrument damage.

How should the exterior of a flexible endoscope be cleaned during manual cleaning?
