Manufacturer Narrative

The customer contacted the siemens customer care center (ccc) to report high atellica im br 27.29 (br) quality control (qc) recovery and high patient recovery on one reagent readypack ((b)(4)) with reagent lot 253.The qc recovery with this reagent readypack was observed to be acceptable prior to march 18, 2021.When the customer changed to a new reagent readypack ((b)(4)) from the same reagent lot 253, qc recovery was acceptable, and the patient results were lower.The results obtained were with the same atellica im br 27.29 (br) assay calibration.Siemens is investigating.The instructions for use (ifu) under the performing quality control and taking corrective action section states the following: "for quality control of the atellica im br assay, use an appropriate quality control material of known analyte concentration with at least 2 levels (low and high) at least once during each day that samples are analyzed.Use the quality control material in accordance with the quality control instructions for use.A satisfactory level of performance is achieved when the analyte values obtained are within the expected control interval for the system or within your interval, as determined by an appropriate internal laboratory quality control scheme.Follow your laboratory's quality control procedures if the results obtained do not fall within the acceptable limits.If the quality control results do not fall within the assigned values, do not report results.Perform corrective actions in accordance with established laboratory protocol." the instructions for use (ifu) under the interpretation of results states the following: "results of this assay should always be interpreted in conjunction with the patient's medical history, clinical presentation, and other findings." the instructions for use (ifu) under the warning section states the following: "do not use the atellica im br assay as a screening test or for diagnosis.Normal levels of ca 27.29 do not always preclude the presence of disease.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

Falsely elevated, atellica im br 27.29 (br) results were obtained for two patient samples as compared to lower results observed when the same samples were re-tested using a new reagent readypack.The customer's quality control (qc) results were observed to be out of range at the time of the incident and repeat testing was performed after acceptable qc results were obtained.The lower repeat br results were reported as the corrected results to the physician(s).There are no reports that treatment was altered or prescribed or adverse health consequences due to the discordant, atellica im br 27.29 (br) results.
