The system was used for treatment.This case is reportable as a mdr due to the reportable malfunction drive tube leak/break.Since this reportable malfunction is only associated with the kit, this mdr will only be against the kit.A batch record review for kit lot j370 was conducted.There were no non-conformances associated with this lot.This lot met all release requirements.A review of kit lot j370 shows no trends.Trends were reviewed for complaint categories, alarm #7: blood leak? (centrifuge chamber) and drive tube leak/break.No trends were detected for these complaint categories.The complaint kit and a photograph were returned for investigation.The smart card was not returned; therefore, the reported alarm #7: blood leak? (centrifuge chamber) could not be verified.The customer provided photograph shows the lower drive tube retainer clip with dried blood on the clip.Inspection of the received kit confirmed the drive leak as dried blood was found on the drive tube near the lower drive tube bearing stop.The drive tube of the received kit had wear marks around the circumference of the lower drive tube bearing stop.The drive tube was installed on a test instrument and the worn section of the drive tube lined up with the edge of the drive tube retainer clip.The evidence to the drive tube is consistent with a misload of the lower drive tube bearing into the retainer clip causing the drive tube to contact the bearing retainer and leak.The root cause for the drive tube leak was most likely caused by not securing the drive tube bearing into the retainer clip during installation of the drive tube by the end user.No manufacturing related defects were identified during this investigation.No further action is required at this time.This investigation is now complete.(b)(4).(b)(6) 2021.
