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 possibly the result of a wbc saturation of the lrs chamber that fell just under the detection threshold for flagging the platelet product for wbc verification, and which occurred before the second scheduled chamber clearing at around 99 minutes into the procedure.Based on the available information, it cannot be ruled out that the higher-than-expected wbc content in the platelet product may have been donor-related.Investigation is in process, a follow-up report will be provided.
