Investigation: terumo bct (b)(4), inc was not able to determine the root cause for the inflated sample bag.Terumo bct (b)(4), inc provided photographs of the set to tbct (b)(4) and it was confirmed that the sample bag was inflated and contained blood.It could not be determined if the white pinch clamp was fully closed on the tubing.The run data file (rdf) was analyzed for this event.Signals in the rdf showed a ¿pressure test error¿ alert was generated during the tubing set test while the system was attempting to positively pressurize the tubing set.It is suspected that this alert was generated because the pinch clamp on the sample bag line was likely not occluding the tubing properly.If the clamp on the sample bag line is not occluding the tubing properly during the tubing set test, air can have a pathway to enter the sample bag.Signals in the rdf also showed that after the operator continued from the ¿pressure test error¿ alert, the tubing set test passed.It is possible that after the ¿pressure test error¿ alert, the operator adjusted the clamp but did not express the air from the sample bag as the sample bag was inflated with a small amount of donor blood upon return to the terumo bct (b)(4), inc.Root cause: review of the run data file showed based on the available evidence, the root cause for the inflated sample bag was not able to be determined.Possible causes include but are not limited to:-the user did not close the clamp when prompted to do so-the user closed the clamp but the clamp was not fully occluding the sample bag line.Corrective action: an internal capa has been initiated to evaluate reports of air in sample bag.
