Additional Manufacturer Narrative
Investigation: the run data file (rdf) was analyzed for this event.The signals in the run data file indicate that the higher-than-expected wbc content in the platelet product was possibly a result of an escape of wbcs from the lrs chamber during the latter portion of the collection.Additionally, the signals indicate that the device had difficulty reaching steady state from the beginning of the procedure, so it cannot be ruled out that the needle line access may have shifted and could potentially have impacted the draw flow rate.Based on the available information, it also cannot be ruled out that the higher than-expected wbc content in the platelet product could be donor-related.Investigation is in process.A follow-up report will be provided.
Event or Problem Description
The customer would like the run data file investigated to determine a possible cause for the elevated white blood cell (wbc) content in the platelet product.There was not a transfusion recipient or patient involved at the time of the residual wbc testing, therefore no patient information is reasonably known at the time of the event.The platelet collection set is not available for return because it was discarded by the customer.
