When should leak testing be performed on an endoscope?

Leak testing is a crucial step in the maintenance and reprocessing of endoscopes, ensuring that these delicate instruments are functioning properly and are safe for use. The correct timing for performing leak testing is before the scope is manually cleaned.

This procedure is essential before any cleaning process because it allows the technician to identify any leaks or damage to the instrument that could compromise its integrity. If a leak is detected, it is crucial to address it before the cleaning process begins. Cleaning a damaged endoscope could lead to contamination and further complications in the reprocessing workflow.

Conducting leak testing after sterilization or disinfection would be redundant and potentially unsafe, as any damage might prevent effective sterilization, resulting in the risk of infection when used on patients. Performing it after patient use also does not allow for the proper handling of the instrument before cleaning, potentially exposing the patient or staff to risks associated with a compromised device. Therefore, the optimal and recommended time for leak testing is before manual cleaning to ensure the safety and functionality of the endoscope prior to its processing.
