Additional Manufacturer Narrative
The field service engineer (fse) was at the customer site on 03-mar-2017 and observed that the rbc (red blood cell) bath had flowed back into the feeder chamber of the dxh 800.The fse replaced a check valve and primed the sweep flow to fix the instrument.The repairs were verified per established procedures.The failure mode is attributed to a defective check valve.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.Patient information was not provided by the customer.(b)(4).
