Additional Manufacturer Narrative

Calibration signals were within expectations.Quality control data were within specified ranges, including the date of the event (b)(6) 2022.There is no indication for a general reagent issue.Upon review of the alarm trace, several "sample foam detection", "sample clot detection" and "sample short" alarms were observed.These are indicators of poor sample quality.Camera images, collected by the analyzer show something swimming on the complained sample as well as dirt in the sampling area.It was further noted that the camera is poorly aligned and the instrument maintenance is overdue.These observations are not related to the reported issue.The investigation determined the issue was consistent with pre-analytical handling issues at the customer site.
