Additional Manufacturer Narrative
The customer reported that the patient was monitored for kappa and lambda for some time using electrophoresis and the alternate non-siemens method.The customer recently started using siemens n latex flc lambda and n latex flc kappa reagents for determination of flc lambda and flc kappa.A siemens headquarters support center (hsc) specialist reviewed the data files on the bn prospec system when the customer previously reported discordant flc lambda and flc kappa results and found no issue.The hsc specialist determined that the save data files contained two quality control (qc) measurements and these results were within expected ranges.The hsc specialist also reviewed the qc kinetics and did not identify any issue.The hsc specialist concluded that there was no indication of a reagent or system malfunction.The cause of the event is unknown.The system and reagents are performing according to specifications.No further evaluation of these devices is required.Mdr 9610806-2018-00035, mdr 9610806-2018-00036, and mdr 9610806-2018-00037 were filed for the same event.
