Event Description

The customer received a false negative blood result on their clinitek advantus instrument compared to manual microscopy of the same sample.The sample was collected the day before testing and stored at room temperature.There is no report of injury due to this event.

Manufacturer Narrative

The customer stated that the sample was collected 24hrs prior to testing and stored at room temperature.Per the reagent instructions for use, "mix the sample before testing and test it within two hours after voiding.If unable to test within the recommended time, refrigerate the specimen immediately and let it return to room temperature before testing." the cause of this event is due to improper sample handling.

Manufacturer Narrative

As the customer has clarified that a test had been run the same day and the sample was not left overnight at room temperature prior to this, siemens no longer has reason to believe the discrepancy is due to user error.Siemens has requested that the customer return remaining reagent in use at the time of the event for further investigation.Investigation will commence once product has been received.The cause of this event is unknown.
