To aid in the investigation of this issue, a picture sample and the affected physical sample were returned for evaluation by our quality team.Through examination of the sample, a syringe was observed missing the barrel label.As the batch number for this syringe could not be identified, a standard production history review could not be performed.The 5ml 306574 syringe is manufactured on line 2.No quality notifications or second samples were identified on this line from october 2021 to present that could have contributed to this defect.Although the exact cause could not be determined, it is possible this incident resulted from an error in the vision system, specifically at the double rejection station.If a syringe has no label, the vision system must identify it and reject the syringe.If there is a failure in the rejection process, the machine automatically stops and the operator must resolve the issue manually.Based on the preventive measures in place, we believe this was an isolated incident with an unlikely chance of recurrence.At this time, further action has not been determined necessary.Our quality team will continue to closely monitor the manufacturing process for signs of this potential defect and any emerging trends.
