Failure analysis was conducted to identify the cause.Evaluation methods employed included visual inspection of returned device, documentation and internal manufacturing process review.From the failure investigation and available information on the reported incident and since the returned kit was confirmed to be meeting the specification and fully functional, the cause of the complaint could not be determined as the actual complaint sample was not returned for investigation.There was no defect found on the returned unused samples.Since the returned devices were functional, no action will be taken.Argon will continue to monitor similar customer complaints and other input sources for potential trends and take the necessary action.
