Manufacturer Narrative
|
Investigation: two used collection bags and a haemonetics lrp6 leukocyte removal filter for platelets were received for investigation.The filter appeared fully saturated and no visual defects were readily apparent.Flow testing confirmed fluid could move through the filter.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.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.This product is not available within the us, but this report is being filed due to an alleged failure that could occur on a similarly marketed device platform cleared for use by the fda.Wbc count is not available at this time.

Manufacturer Narrative
|
This report is being filed to provide additional information in h.6 and h.10.Investigation: two used collection bags and a haemonetics lrp6 leukocyte removal filter for platelets were received for investigation.The filter appeared fully saturated and no visual defects were readily apparent.Flow testing confirmed fluid could move through the filter.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 root cause assessment was performed for this complaint.Based on the available information a definitive root cause could not be determined but it is likely due to one or a combination of the possible causes listed below: - donor specific physiology - sampling, calculation, or other process error - rbc spillover - centrifuge stopped - rbc detector calibration error - 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.
