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 due to plasma line occlusion.The centrifuge stop during blood prime due to 'centrifuge pressure too high' alert may have introduced an airblock in the plasma centrifuge line.Plasma line occlusion results in more volume being drawn through the lrs chamber than intended, which disrupts leukoreduction.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 white blood cell (rwbc) testing, therefore no patient information is reasonably known at the time of the event.Donor unit #: (b)(6).The platelet collection set is not available for return because it was discarded by the customer.
