Investigation: the device history records (dhr) were reviewed for this lot.There were no events noted in the dhr that would have contributed to the elevated wbc count experienced by the customer.The run data file (rdf) was analyzed for this event.Root cause: the signals in the run data file did not indicate a conclusive cause for the higher-than-expected wbc content in the platelet product reported for this collection.No unusual process variable was identified and the signals in the run data file indicate that the trima accel system operated as intended.Based on the available information, it cannot be ruled out that the higher-than-expected wbc content in the platelet product could be donor-related.It also cannot be ruled out that a sampling, calculation, or other process error could have contributed to the higher-than-expected wbc content in the platelet product.
