    INVESTIGATION: ONE SET OF BLOOD BAGS WITH THE FILTER FROM THE COLLECTION SET WAS RETURNED FOR EVALUATION. THE LEUKO REDUCTION FILTER WAS TESTED FOR FLOW RATE AND AIR LEAKS. A SWIFT FLOW RATE OF 70 ML/MIN WAS NOTED AND IT WAS CONFIRMED THERE WERE NO AIR LEAKS. THE MANUFACTURING RECORDS, TEST RECORDS, AND INSPECTION RECORDS WERE REVIEWED FOR ABNORMALITIES AND NONE WERE FOUND. THE RECORDS REGARDING THE PARTICULATE REMOVAL RATES OF THE FILTER MEMBRANES WERE REVIEWED. ALL MEMBRANES CONFORMED TO ESTABLISHED SPECIFICATION. SHIPPING TESTING WAS PERFORMED ON THE RESERVE SAMPLES FROM THE REPORTED LOT NUMBER. THE RESERVE SAMPLES WERE ALSO VISUALLY EXAMINED AND THE SOLUTION VOLUME AND SOLUTION COMPOSITION WERE TESTED WITH NO ABNORMALITIES NOTED. ROOT CAUSE: A DEFINITIVE ROOT CAUSE FOR THE OBSERVED ELEVATED WBC COUNT REMAINS UNDETERMINED AT THIS TIME. BASED ON THE AVAILABLE INFORMATION, IT CANNOT BE RULED OUT THAT THE HIGHER-THAN-EXPECTED WBC CONTENT IN THE WHOLE BLOOD PRODUCT COULD BE DUE TO AN OCCLUSION,BLOOD MAY HAVE BEEN FILTERED BY A SMALLER THAT USUAL FILTER AREA. AS A RESULT, LINEAR SPEED MAY HAVE INCREASED AND LEUKOCYTE LEAKAGE MAY HAVE OCCURRED. AS AN INCREASE OF WBC CONTAMINATION COMPLAINTS WERE NOTED FROM PREVIOUS LOT NUMBER, FURTHER INVESTIGATION WAS PERFORMED. INVESTIGATION RESULTS INDICATED THAT THE CAUSE OF HIGHER-THAN-EXPECTED WBC CONTENT IN THE WHOLE BLOOD PRODUCT WAS DUE TO THE MAXIMUM PORE SIZE OF THE FILTER MEMBRANE IS LIKELY TO INCREASE ACCORDING TO THE COMBINATION OF MULTIPLE PARAMETERS IN MANUFACTURE OF LEUKOREDUCTION FILTER MEMBRANES AND WBC CONTAMINATION IS LIKELY TO OCCUR FREQUENTLY IN THE PRODUCT LOTS OF WHICH THE MAXIMUM PORE SIZE OF THE FILTER MEMBRANE HAS INCREASED. THE INSTRUCTIONS FOR USE PROVIDE A CAUTION TO NOT SQUEEZE OR APPLY PRESSURE TO THE FILTER WHILE IT IS ATTACHED TO THE BAG CONTAINING THE FILTERED BLOOD AND ALSO TO CLAMP THE BLOOD FILLED TUBING BEFORE BLOOD ENTERS THE FILTER IN ORDER TO AVOID LEUKOCYTE LEAKAGE. CORRECTIVE ACTION: AN INTERNAL CAPA HAS BEEN INITIATED TO REVIEW THE COMBINATION OF THE MULTIPLE PARAMETERS SUGGESTED THE TENDENCY OF THE INCREASE IN THE MAXIMUM PORE SIZE OF THE FILTER MEMBRANE. MANUFACTURING SPECIFICATIONS WERE UPDATED TO NARROW THE RANGE OF THE PARAMETERS IN MANUFACTURE OF FILTER MEMBRANES AND IT WAS CONFIRMED THAT THE APPROPRIATE LEVEL OF THE MAXIMUM PORE SIZE OF THE FILTER MEMBRANE WAS ACHIEVED.
