Manufacturer Narrative

The last calibration performed on (b)(6) 2023, and the quality controls results do not indicate a general reagent issue.Upon review of the alarm trace, no general instrument issue was detected.It was determined that the tip of the sample probe had a crystal, indicating inadequate daily sample probe manual cleaning by the operator.The crystals could be contaminating the aspirated sample but would not cause the observed event.The investigation could not identify a product problem.The cause of the event could not be determined.
