Additional Manufacturer Narrative
H6: investigation summary: bd had not received samples for evaluation.Therefore, 10 retention samples of the incident lots were selected from bd inventory for evaluation and upon completion, no issues relating to erroneous results were observed.There were no difficulties encountered during blood collection and all tubes appeared to exhibit proper fill.Bd was unable to duplicate or confirm the customer¿s indicated failure mode (erroneous results) because the defect was not evident in the testing of the customer lot samples.Replicates of both retain and control samples were acceptable in terms of both precision and accuracy.Based on a review of the device history record for the incident lot, all product specifications and requirements for lot release were met.There were no related quality issues during manufacturing of the product.This complaint is not confirmed for draw volume or erroneous results.Bd was not able to identify a root cause for the indicated failure mode.A discard tube must be used when using a winged blood collection set for venipuncture in order to fill the blood collection set tubing¿s ¿dead space¿ with blood.It is not necessary to fill the discard tube completely.This step will ensure maintenance of the proper blood-additive-ratio of the specimen.The discard tube should be a non-additive or coagulation tube.As noted in our instructions for use (ifu), the overfilling or under filling of tubes will result in an incorrect blood-to-additive ratio and can lead to incorrect analytic results or poor product performance.If the specimen is drawn with a syringe, it is important not to over fill the bd vacutainer® citrate tube.Allow the tube to draw the blood from the syringe using a bd vacutainer® blood transfer device if available.Do not force blood into tube.Do not fill tubes from other tubes or combine two partially filled citrate tubes.Complete and adequate mixing is required immediately after phlebotomy to prevent clotting.Inadequate number of inversions (as stated in ifu) after phlebotomy will not allow proper mixing of blood and anticoagulant.In addition, following the proper order of draw is essential.Adherence to the recommended specimen handling and processing steps will facilitate acceptable specimen quality and overall performance for reliable analytical outcomes.H3 other text : see h.10.
