Additional Manufacturer Narrative
The run data file (rdf) was analyzed for this event and no abnormalities were observed that would indicate the reason for the leukoreduction failure.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 red blood cell (rbc) 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 collection set is not available for return because it was discarded by the customer.
Additional Manufacturer Narrative
This report is being filed to provide additional information in h.6 and h.10.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.Root cause: a definitive root cause for the observed leukoreduction failure remains undetermined at this time.The analysis of the run data file did not find a conclusive cause for the higher-than-expected wbc content in the rbc 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 rbc product could be donor-related.Other possible causes could be a post collection process error or a malfunction of the filter.
