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.Wbc count is not available at this time.The platelet collection is not available for return because it was discarded by the customer.

Manufacturer Narrative

This report is being filed to provide additional information in h.6 and h.10.Investigation: the lot number was not provided, therefore, a dhr search could not be conducted for this specific incident.All lots must meet acceptance criteria for release.Root cause: a root cause assessment was performed for this complaint.There are various reasons for elevated wbc levels in collected product such as donor factors, kit misloads, airblocks, disposable set deviations, paused centrifuge, or other processing difficulty in maintaining the steady state necessary to efficiently separate blood components.Regarding donor factors, there appears to be patterns with repeat donors that produce platelet products with high wbc counts.Saturation events leading to elevated wbcs in collected product are also possible if the donor pre-counts are entered falsely much lower than actual as this can cause the lrs chamber to fill before the system expects and wbcs to escape before detection.Misloading of a set or disposable set deviation may cause a plasma line occlusion or an air block within the centrifuge which may lead to the white blood cells getting flushed out of the lrs chamber into the product.
