Investigation summary: we have been provided with the affected samples.A leakage through the plunger rod was observed in the provided samples.We could not determine the exact root cause due to the presence of dry blood inside the syringes.The samples were not decontaminated.We have reviewed our production and inspection records and have established that all production and quality processes were carried out normally.Neither qn nor ncmr's.Syringes were packed in machine nº2020 (november 14th - 16th, 2017).Syringes were assembled in machines nº4255, nº4254, nº4237, nº4236, and nº4220, in lot #7317654 (november 13th - 20th, 2017).Research has found no problems, defects or qn related to the reported issue.We have also reviewed the barrel lot #7318864, #7311693, #7296611, and no problems, defects or qn were found.We have also reviewed the plunger lots #7318868, #7311697, #7296627, and no problems, defects or qn were found.After the evaluation of the received sample, we conclude that the possible cause of the problem could be produced as a consequence of a damage in the plunger lip.This could be produced during the handling of the product through the manufacturing process or in the plunger assembly machine.Not able to determine.Damage in the plunger lip produced during the handling of the product through the manufacturing process or in the plunger assembly machine.We can ensure that the probability of finding this kind of defect is an isolated issue and any recurrence is really unlikely in our products since review syringe dhr showed no indication of the alleged defect, considering our in-coming and in-process inspection and since this is the first time this lot is reported for this defect, no actions are required.
