Manufacturer Narrative

The calibration performed on (b)(6) 2023 was acceptable with no alarms.On (b)(6) 2023 the customer recalibrated the affected reagent pack twice and the calibration signals shifted higher.The customer replaced the reagent pack and recalibrated twice, with the first calibration's signals matching their initial pack, and the second calibration receiving much higher signals.On (b)(6) 2023 the customer used a new reagent pack and recalibrated it with freshly made calibrators.The calibration was successful with no alarms.On (b)(6) 2023 the quality controls were successful with no alarms.On (b)(6) 2023 the quality controls were partially out of range.On (b)(6) 2023, quality controls were successfully performed on the new reagent pack with no alarms.Upon review of the alarm trace, abnormal probe-sucking errors were observed.These alarms are indicators of possible poor sample quality.After changing the reagent pack and performing a new calibration, the issue did not re-occur.The investigation could not identify a product problem.The cause of the event could not be determined.
