Manufacturer Narrative

Siemens filed the initial mdr 1219913-2019-00281 on december 27, 2019.April 09, 2020 additional information: the sid (b)(4) was run for thcg and result of 65.6 was generated.Two of the three levels of quality control (qc) were out of range that day.The qc results were as follows: result units: miu/ml level 1 (k40981) result: 6.4 (3.51 - 11.1) level 2 (k40982) result: 40 (19.1 - 31.1) level 3 (k40983) result: 410.2 (153 - 225) the patient sample was repeated on another instrument and a result of 4.8 was generated and considered to be the correct result.The qc level 2 control was also repeated and a result of 24 was generated which is within the range.Review of the ic debug logs showed that the patient sample ran without error.Per the service report, the reagent probes were replaced and realigned.Based on the information given the incorrect result was due to an increase in rlu therefore we would not expect to see any issues with the aspiration traces and replacing and realigning the reagent probes would not correct this issue.There was no definitive root cause found as a result of the investigation.Follow up with the local team indicated that the instrument is operational, and the customer is reporting thcg results.The instrument is performing within specifications.No further evaluation of the device is required.Mdr 1219913-2019-00282 supplemental report 1 was filed for the same event.
