Initial mdr 1219913-2023-00083 was filed on (b)(6) 2023 reporting a customer from outside the united states observed discordant elevated results when running atellica im enhanced estradiol compared to repeat testing of the samples on alternate atellica im analyzers with lot 092.Additional information may 12, 2023: the customer reported falsely elevated patient results on atellica im enhanced estradiol (ee2) assay with reagent lot 090.On (b)(6) 2023, biorad immunoassay plus quality control (qc) lot 85310 recovered high and outside acceptable ranges on atellica im ih00895.A lookback of patient samples tested since qc was last in range was performed.They repeated multiple patient samples on other atellica im analyzers, and identified discordant results.The repeat results were lower than initial results and were believed to be accurate.The troubleshooting actions performed by the customer included replacing the ee2 reagent pack.The customer no longer had any additional inventory of ee2 reagent lot 090 so they started using lot 092.This new reagent lot calibrated successfully and qc recovered within range.The customer suspects an issue with the shipment of ee2 lot 090 that was in use from a shipment received in (b)(6) of 2022.The details related to this shipment were requested but were not available.Siemens reviewed internal release data and field data for ee2 lots 090 and 092.These two lots are performing acceptably and are not statistically different from one another.A potential product performance issue has not been identified.The customer is operational.This issue was resolved by routine troubleshooting.In section h6, the investigation finding, and investigation conclusion codes were updated.
