Event Description
|
The customer informed siemens that ca 15-3 patient samples were falsely diluted on the advia centaur xpt instrument.Upon review, the customer noticed an incorrect dilution point of 10 had been set in the test definition under the ranges tab and the instrument performed unnecessary auto-dilutions.The diluted patient results were reported via the laboratory information system (lis) and were not questioned by the physician(s).The customer did not perform repeat testing.On (b)(6) 2018, discordant results that were reported were amended to the undiluted value/correct value.There are no known reports of patient intervention or adverse health consequences due to the falsely diluted ca 15-3 patient sample results.
