Additional information - other relevant history.The actual sample involved is not available for evaluation and the specific lot number is not known.A search of shipping records was performed to identify any product lots shipped to the customer three (3) months prior to the event occurrence date.A retrospective record review of those lots identified one (1) lot (14dmlb003) that was part of a recall due to bioburden and endotoxin issues (dietzia species), and was recalled on may 15, 2015.A definitive conclusion regarding the involvement of the product could not be reached without a physical examination of a complaint sample.Therefore, the manufacturing plant was not able to confirm a possible association between the naturalyte liquid bicarbonate concentrate product and the patient death.The post market surveillance department has received patient medical records and treatment data sheets for review.A clinical investigation (ci) is in process.A supplemental mdr will be submitted upon completion of this activity.
