The investigation conducted is commensurate to The difficulty and really should be done by a multi-practical team and well documented, with sufficient efficiency checks implemented to validate the proposed steps.

In this case, the preventative action is likely to be to evaluate the education software for laboratory personnel. Or was the pipette from tolerance? What then was the frequency of calibration? Was the pipette subjected to significant daily use? The corrective action to deal with the immediate situation would be to employ An additional pipette that is definitely in calibrated status.
