H.6 investigation summary: the complaint investigation for fit issue with the swab when using the bd molecular swab collection kit 100ea (ref #443925) unknown lot number was performed by the verification of complaints history.No kit lot number or picture was provided for investigation, which was thus limited.However, in a previous investigation, it was determined that off-label use of the swab could lead to issues such as those described by the customer.Indeed, when the swab¿s score mark is aligned with the edge of the tube, it breaks easily at the black line which is what is expected.However, when the swab is fully inserted into the tube, it can break above the black score mark resulting in the swab sticking out of the tube.As documented in the bd molecular swab collection kit package insert p0246, the swab must not be inserted at the bottom of the sample buffer tube but must be inserted so that the score mark indicated by the black line is at the lip of the tube.The swab shaft must be broken at the score mark so that the swab drops into the tube.In comparison, review of the bd max¿ uve specimen collection kit (443376) which is the collection kit previously used by the customer with the bd max¿ vaginal panel or the bd max¿ ctgctv assays, revealed that this other collection kit used a different swab which needed to be fully inserted into the sbt before breakage.This differs from the bd molecular swab collection kit procedure and could make the shaft breakage difficult, thus explain the issue.Based on the results of this investigation, the cause of the issue is suspected to be an improperly broken shaft due to an improper technique used for shaft breakage.There is no indication of defective swab issue based on the analysis of the complaints received on bd molecular swab collection kit 100ea product.The root cause was not identified.Bd cannot confirm the complaint based on the investigation that was performed.H3 other text : see h.10.
