Additional Manufacturer Narrative
The investigation has determined that a non-reproducible, higher than expected troponin i result was obtained from a single patient sample using vitros immunodiagnostic products troponin i es reagent pack lot: 6445 on a vitros xt 7600 integrated system.A definitive assignable cause of the event could not be determined.Based on historical quality control results, a vitros tropi es lot: 6445 performance issue is not a likely contributor to the event.Furthermore, continual tracking and trending of complaint data has not identified any signals to suggest there is a systemic quality issue with vitros tropi es reagent lot: 6445.However, the customer does not process a control fluid with a troponin i concentration at, or below the url.Therefore, the performance of the vitros tropi es reagent lot: 6445 at, or below the url concentration of 0.034 ng/ml (ug/l) cannot be determined and a reagent issue could not be entirely ruled out as contributing to the event.As no vitros tropi es within run precision was performed on the vitros xt 7600 integrated system upon request, an instrument issue cannot be ruled out as a contributing factor of the event.Additionally, the condition code pes-623 pre-well wash % volume exceeded limit, had posted on the vitros xt 7600 system around the timeframe of the event.Pre-analytical sample processing could not be ruled out as a contributing factor as it is unknown if the customer was following the sample collection device manufacturer recommended centrifugation protocol.Improper pre-analytical sample handling could have contributed to the event.It is possible that cellular debris, due to poor sample preparation, was present in the affected sample, although this could not be confirmed.
