Received 2rk of 456087p/b210137g for evaluation.Received customer pictures and videos.We have no further complaints on the material/batch.A check of quality, production, and maintenance documents revealed no deviations in relation to the reported error.Samples were tested, according to gbo standard testing procedures, with regards to correct assembly, level mark, filling level, draw volume and additive content according to iso 6710 'single use containers for venous blood specimen collection' and clsi gp39-a6 regulations for 'evacuated tubes and additives for blood specimen collection'.Tubes were verified to be correctly assembled and had the correct fill guideline position.Greiner fill mark provides a visual control opportunity for the phlebotomist and for the lab personnel to check for proper volume collection of specimen.Both standards specify the draw volume to be within +/- 10% range of the nominal fill volume.No visual deviation in fill volume, sporadic low or high fill, could be observed in the tested samples.All tubes tested filled within the +/-10% tolerance range.Additive content was found to be within specification in all tested samples.No deviations could be observed in the tested samples.Some of the samples were evaluated in a blood draw.Samples were centrifuged using recommended gbo parameters within 2 hours.No oily residue on the top surface of the plasma, gel droplets, and fibrin as described by the customer could be observed.The complaint cannot be duplicated on the returned samples.Corrected data: h3: samples received; h6: type of investigation, investigation findings, investigation conclusion.H10: manufacturerer narrative.
