A customer contacted the ortho clinical diagnostics (ortho) technical solution center (tsc) to report a higher than expected vitros ckmb result was obtained from a patient sample using vitros ckmb slide, lot 4912-0254-4854, on a vitros 5600 integrated system.Vitros ckmb result of 40 u/l versus the expected result of 7 u/l biased results of the magnitude and direction observed may lead to inappropriate physician action if they were to occur undetected.The higher than expected vitros ckmb result was obtained during a patient correlation and was not reported from the laboratory.There was no allegation of patient harm as a result of this event.This report corresponds to ortho clinical diagnostics inc (ortho) complaint number (b)(4) and reportability assessment (b)(4).

The investigation determined that a higher than expected vitros ckmb result was obtained from a patient sample using vitros ckmb slide lot 4912-0254-4854 on a vitros 5600 integrated system.The assignable cause of the event cannot be determined with the information provided.Vitros ckmb lot 4912-0254-4854 was a new lot in use at the time of the event with limited quality control data, and no historical vitros ckmb quality control data was not provided to confirm performance of the customer's current in-use lot.Qc data was provided for a single day and the results were unexpected for both the customers current vitros ckmb lot 4912-0253-3562, and the new vitros ckmb lot 4912-0254-4854.The limited qc data that was provided for 05 feb 2023 was not as expected for either the in-use lot or the lot in question, and the information that was provided indicates that it is possible another level of fluid was in use, although this could not be confirmed.The customer additionally did not provide any qc fluid handling information.Therefore, neither a qc fluid sample mix up nor a fluid handling issue can be ruled out as a contributor to the unexpected qc results.Additionally, no data was provided for the date of the event on (b)(6) 2023.Therefore, an issue with vitros ckmb lot 4912-0254-4854 in use at the customer site on the day of the event cannot be ruled out as a contributor to the event.However, continual tracking and trending does not indicate a systemic issue with vitros ckmb lot 4912-0254-4854.Although a diagnostic precision was not processed on the vitros 5600 integrated system, it is not expected that an instrument issue would be a contributor to the event as the patient samples were run on both reagent lots concurrently.
