[139069344]
The customer contacted a siemens customer care center and reported that an elevated free light chains (flc), type lambda (flc lambda) result was obtained on a patient sample on a bn prospec system. The customer previously contacted siemens regarding discordant flc lambda results obtained for this patient and mdrs 9610806-2019-00006 and 9610806-2019-00007 were filed for the discordant results previously obtained on the other samples from this patient. Siemens previously determined that there was no indication of a system malfunction and that the cause of the discordant flc lambda results was sample specific. The customer did not have the sample for further investigation. On (b)(6) 2019, the customer sent another sample from the same patient for further investigation; siemens further investigated the issue and a study was performed on the affected sample. The sample was tested on a bn prospec system using the same reagent, and the flc lambda result confirmed the elevated recovery observed by the customer. Analysis of the sample portrayed that the flc lambda determinations were correctly evaluated by the bn prospec system; flc lambda concentration was present in a large protein complex in the sample. The system is performing according to specifications. No further evaluation of this device is required. Mdr 9610806-2019-00008 was filed for the elevated flc lambda result obtained on the week of (b)(6) 2019 on another sample from the patient. Supplemental mdrs 9610806-2019-00006_s2 and 9610806-2019-00007_s2 were filed for the same issue.
