Verify and Document

After identifying and correcting a problem, verify the correction by retesting the controls. Generally, the controls are run at the beginning of a run. If the new QC values are in control, repeat patient samples from the out-of-control run as necessary. Finally, document the out-of-control event along with the corrective action.
