Certified Endoscope Reprocessor (CER) Practice Exam

Leak testing of endoscopes should be performed after every procedure to ensure the integrity of the device. This testing is crucial because it verifies that there are no breaches or damages in the endoscope that could affect the cleaning and disinfection process. If an endoscope has leaks, it can allow contaminants to enter the internal components, which could lead to infection risks for patients.

Conducting this test after each use helps identify any potential issues immediately, allowing for timely repairs before the endoscope is utilized again. It is an essential step in safeguarding patient safety and ensuring the endoscope functions correctly in subsequent procedures.

Leak testing at different stages, such as before manual cleaning or during the cleaning process, would not provide the same assurance that the endoscope has maintained its integrity throughout its last use. Therefore, the protocol of performing leak testing after every procedure aligns with industry standards for infection control and device safety.
