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.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.The platelet collection is not available for return because it was discarded by the customer.

Manufacturer Narrative
|
This report is being filed to provide corrected information and additional information.Updated root cause: a definitive root cause for the leukoreduction failure remains undetermined at this time.Possible causes include but are not limited to:- rbc spillover- centrifuge stopped- rbc detector calibration- possible air block- the orientation of the tubing as loaded in the centrifuge hex holder and the compromised structural integrity of the plasma tubing.Effectively, there is a certain orientation in the hex holder that allows for the rbc line to lie on top of the plasma line and, under certain flow conditions, may cause the plasma line to pinch off.This in turn causes higher flow through the lrs chamber, which may lead to elevated levels of wbcs in the platelet product.- donor specific variables.
