Investigation: a review of the device history record (dhr) for this unit showed no irregularities during manufacturing that were relevant to this issue.The phenomenon of bacterial contamination in blood products, especially platelets, is unfortunately known to occur.With current technologies, given the nature of micro-organisms on human skin and the mechanical act of piercing the skin coupled with the fact that platelets must be incubated at room temperature it is not possible to completely eliminate this phenomenon from occurring.Per internal documentation, the devices terumo bct manufactures in lakewood, co to collect, separate and store blood products are terminally sterilized to an sal of < 10-6.Additionally, a sterility assurance system has been designed and employed to ensure this sal will be achieved for every lot of product manufactured.Therefore it may be concluded that in lieu of a catastrophic failure occurring in the manufacturing process, bacterial contamination observed in collected blood products from terumo bct devices is due to the inherit hazard of collecting blood as it relates to bacterial contamination.Root cause: a definitive root cause could not be determined.Possible causes include but are not limited to:- poor phlebotomy venipuncture- post processing lab qc sampling/handling techniques.
