Consequences of quality control
External
quality assurance
● If a laboratory does not receive the certicifate, the cause must be clarified and eliminated.
Internal
quality assurance
● If the retrospective analysis shows any trends, the cause has to be clarified.
● If the mean value of all differences is greater than the control value, further results can only be used for clinical diagnosis after the cause has been clarified and eliminated.
