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.Donor unit #: (b)(6) 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.
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 likely a result of an escape of wbcs from the lrs chamber during the collection.Based on the signals, it cannot be ruled out that this disruption may have been due to an occlusion or air block in the plasma line in the centrifuge that disrupted the steady state of the system.Additionally, 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.
Additional Manufacturer Narrative
This report is being filed to provide additional information in d.4, h.6 and h.11 and updated information in g.1.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 likely a result of an escape of wbcs from the lrs chamber during the collection.Based on the signals, it cannot be ruled out that this disruption may have been due to an occlusion or air block in the plasma line in the centrifuge that disrupted the steady state of the system.Additionally, it also cannot be ruled out that the higher-than-expected wbc content in the platelet product could be donor-related.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.Root cause: the signals in the run data file indicate that the higher-than-expected wbc content in the platelet product was likely a result of an escape of wbcs from the lrs chamber that began near the start of the collection.Based on the signals, it cannot be ruled out that this disruption may have been due to an occlusion or air block in the plasma line in the centrifuge that disrupted the steady state of the system.Additionally, it also cannot be ruled out that the higher-than-expected wbc content in the platelet product could be donor-related.
