Bacterial contamination of platelet products, both single donor apheresis platelet units and whole blood-derived platelet pools, continues to occur despite preventive measures. While some advances have been made in decreasing the rate of bacterial contamination of platelet units, particularly through diversion methods and early culture, a great deal remains to be done to eliminate the problem. Diversion methods have decreased contamination rates associated with skin commensal organisms. In this study10 single donor platelet units were collected from eligible platelet donors using the standard collection procedures of Blood Transfusion Center of Cairo University hospitals. Units were examined for bacterial contamination at days ( 0 , 5 , 7) of collection Using our new method platelet pan genera detection (PGD) test and bacterial culture as a comparative method. All examined units were negative for bacterial contamination up to day 7 according to results revealed by both platelet (PGD)test and bacterial culture. This means that we can extend shelf life of platelet units up to 7 days instead of 5 days and units can be examined for bacterial contamination immediately before transfusion to insure safety of transfused units.
