Additional Manufacturer Narrative
The initial inspection of the dxh800 instrument by the field service engineer (fse) on 22-sep-2017 found that the rbc apertures were nearing maximum output and bubbles were also observed in the diluent input.The fse replaced the rbc bath assembly and the tubing between the diluent sensing board and the y-fitting to resolve the reported issue.Service activity performed was verified to meet the specified requirements per established procedures.Patient information was not provided by the customer.Beckman coulter is conducting a retrospective review of its global service records, to ensure that the records had been adequately evaluated for potential complaint information and any warranted follow-up action, including mdr reporting.  this mdr report is a result of that retrospective review.An improvement for plt flagging was developed and released as a part of a software update to the dxh800 that is designated v3.2.1 on 22-dec-2017; approximately 11.5% of the worldwide product installed base has been upgraded as of 13-jul-2018.Due to an increase in the number of complaints received related to unflagged erroneously high plt patient results released from the lab, bec anticipates that a field action will be warranted.The anticipated field action will include a software patch for the improvement for the plt flagging component of v3.2.1, which will expedite installation of this improvement for the rest of the installed base.(b)(4).
