Manufacturer Narrative

A us customer observed an elevated atellica im 1600 br (br 27.29) result for a patient sample compared to repeat testing of a different draw.Siemens is investigating.The limitations section of the instructions for use states the following: "note do not interpret levels of ca 27.29 as absolute evidence of the presence or the absence of malignant disease.Before treatment, patients with confirmed breast carcinoma frequently have levels of ca 27.29 within the range observed in healthy individuals.Additionally, elevated levels of ca 27.29 can be observed in patients with nonmalignant diseases.Measurements of ca 27.29 should always be used in conjunction with other diagnostic procedures, including information from the patient's clinical evaluation.".

Event Description

Customer observed an elevated atellica im 1600 br (br 27.29) result from a sample that was considered discordant with the repeat result on redraw.Elevated result was reported to the physician and not questioned.There are no known reports of patient intervention or adverse health consequences due to the discordant br 27.29 result.

Manufacturer Narrative

The initial mdr was filed on (b)(6), 2021.The initial mdr incorrectly referenced catalog #10995282 in section d4.Section d4 of this report has been updated with the correct catalog #10995478.Additional information - march 08, 2022.A us customer observed an elevated atellica im 1600 br (ca 27.29) lot 257 result from a sample upon comparison with a repeat result on a different atellica im after 20 days of sample collection.A review of the br control data indicated that control recovery was high (the low control recovered 26.27 u/ml, 35% above target; the mid control recovered 111.61 u/ml, 8% above target), but in range when using primary readypack p04725705001708.A different br primary readypack recovered the controls closer to target (the low control recovered 19.76 u/ml, 2% above target; the mid control recovered 111.61 u/ml, 0% from target), using the same ancillary readypack, calibration, and qc barcoded tubes that had been used earlier with primary readypack p04725705001708.So the ancillary readypack, calibration, and qc barcoded tubes did not cause the shift in qc results.Primary readypack p04725705001708 was used to generate the initial results for a sample in question on september 03, 2021.A review of logs by siemens did not show any issues that would indicate the instrument caused elevated qc or patient results.There is no sample that can be sent to siemens healthineers for evaluation.Primary readypack p04725705001708 had been on the analyzer for 23 hours when the control data was generated and for 24 hours when the patient sample was tested so well within the 3 day recalibration period.Siemens could not determine the cause for the difference in results with the sample but primary readypack p04725705001708 appeared to be recovering high on september 03, 2021 for some unknown reason.Atellica im br kit lot 257 expired on november 10, 2021.The cause(s) of the variability of patient sample recovery run to run seen by the customer when using atellica im br kit lot 257 could not be determined but siemens cannot rule out pre-analytical factors, a sample issue, or normal assay performance.Based on the investigation, no product problem was identified.The customer is operational.No further action is required.In section h6, investigation findings and investigation conclusion codes were updated based on the investigation results.
