The pall data 5 software presented an o2 level reading of "pass" for a sample pouch test result.The test result values were indicative of an invalid test result according to cbc standard operating procedure.Upon completion of investigations, it was discovered that the sampling membrane had not been penetrated; therefore, the sample pouch had not been sampled for testing using the pall ebds oxygen analyzer.The system relies on a manual check by the user to detect the invalid result.No safeguards are provided by the system to prevent products with invalid results from being released as acceptable.
