6.3.5.7 - QC Result analysis
Authorized staff should identify and differentiate acceptable/unacceptable random errors and trends and/or
shifts in systematic errors from the statistical data. Depending on the users Quality Control Procedures
analytical results could be accepted or rejected.
Changes in QC results can be gradual or abrupt. Gradual changes can be caused by contamination and
incidental environmental variations. Abrupt changes can be caused by change of QC material batch or
possible hardware errors.
If results are continuously out of range due to significant difference between calculated mean and control
value, but the statistics show precise results with small deviations, it should be considered to expand the
acceptable assay range with QC Settings .
If results are incidentally out of range it is advised to perform a daily maintenance and/or fill and clean step
and then perform another QC sample step before releasing patient results.
If results are not sent to the LIMS QC Results can be exported to MS Excel CSV files for further analysis in
lab's own Quality Control data system.
