Manufacturer Narrative

Investigation: the run data file (rdf) was analyzed for this event.There was no conclusive root cause identified for the higher-than-expected wbc content in the platelet product reported for this procedure, however the signals in the run data file indicate that the higher-than-expected wbc content was possibly the result of a wbc saturation of the lrs chamber which occurred just before the start of second scheduled chamber clearing and which fell just under the detection threshold for flagging the platelet product for wbc verification.It is also possible that the higher-than-expected wbc content in the platelet product could be due to the entered donor platelet pre-count being lower than the actual donor platelet pre-count.Additionally, 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.

Event 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 id (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.
