Manufacturer Narrative

Request from fda: we received mdr regarding erroneous patient results using the cobas u 601 urine analyzer.In the original mdr, it is stated that follow up/corrective actions for the event are currently ongoing, but in the mdr supplement #1, it is stated that the investigation did not identify a product problem.Request from fda: could you clarify whether the capa investigation is complete, what was the probable cause of the issue and if there were any corrective actions taken? response from manufacturer: the investigation is complete and a product problem was not identified.There was no capa initiated.The mdr incorrectly specified that corrective actions are ongoing.A supplemental report will be submitted to correct this.Response from manufacturer: the customer reported that after an electrical failure in the building, there was a mismatch between two results.The customer noticed the issue and the results were deleted from both the lis and the analyzer.Response from manufacturer: the probable cause of this event could not be determined.The problem report was provided by the customer but data from the date of the event was not included.The instrument periodically overwrites this data.Also additional data files were requested but not provided by the customer.These files are important when investigating a possible sample mismatch.Response from manufacturer: typically, occurrences of sample mismatch can be traced back to use error.However, without the data files from the instrument this could not be confirmed.
