Reason

The recall was initiated due to Beckman Coulter receiving a report of results that were associated with incorrect patient identifications when two sample racks advanced into the sample presentation area in one push. The first rack of the two was not scanned. This is referred to as a "pushed pair." If a pushed pair event occurs, results may be associated with the incorrect patient identification.

Action

Beckman Coulter sent an Urgent: Field Safety Notice Product Correction letter dated January 26, 2011, via US Postal Service to all affected customers. The letter identified the product, the problem, and the action to be taken by the customer. Customers were instructed to: 1. To prevent a pushed pair, be sure your sample racks are free of debris prior to use. Do not apply additional labels to the sample racks. Extra labels can obscure the edges of a sample rack, or obstruct the gap between two racks. Be sure sample labels do not extend beyond the edges of a sample rack; 2. If a pushed pair occurs on the UniCel DxI system, the system generates a yellow Event Log message - Clear the presentation tray and press ROUTINE button. This Event Log message is associated with a variety of common Sample Presentation Unit (SPU) errors. For that reason, you must review the Event Log details to confirm the pushed pair event has not occurred; 3. Detach the Appendix included with this notification and store it near your UniCel DxI system. Use the Appendix as a reference if you suspect a pushed pair event has occurred on your system. Beckman Coulter also requested their customers share the recall information with their laboratory staff, and retain pages 1 and 2 of this notification as part of your laboratory Quality System documentation. For questions regarding ththe recall notification, customers were instructed to contact Beckman Coulter Customer Support Center on the Beckman Coulter website at http://www.beckmancoulter.com/customersupport/support, or call 1-800-854-3633 in the United States or Canada. Outside the United States and Canada, contact their local Beckman Coulter Representative.
