Recall Z-1257-2023

Reason for recall

An increased incidence of damage to the nut band from a new vendor (Boamax) has led to an increased volume of complaints from consignees regarding wash arm motion failures, system check failures, and/or assay performance leading to a remote probability of delayed results or reporting erroneous patient results. The subject nut bands were found to not meet the firm's specifications for hardness and had the incorrect material grain direction. Affected instruments were manufactured from December 28, 2017 to October 19, 2022 or had their nut bands replaced during the same period.

If Wash Arm Motion Errors are observed or if the nut band appears to be damaged in any way, specific instructions are provided. The recalling firm will replace the affected nut bands for all Access 2 Immunoassay Systems listed in Appendix A of the letter. A service representative will contact the consignee to schedule the wash arm lead screw nut band replacement. The information in the notification is to be shared with the laboratory staff and retained as part of the laboratory Quality System documentation. If the affected device has been forwarded to another laboratory, the consignee is requested to provide them a copy of the letter.
