Calibrator and QC should be different Only then can you assess your own lab and its equipment’s and check accuracy Calibrator is used to calibrate, or adjust a measurement procedure. A control is used to monitor an analysis performance
Calibrators and Controls ensure reliability and consistency of test results and the analysis system Both cannot be used interchangeably as both have different roles If we use the same material as control and calibrator , it will not solve the purpose of checking the complete analysis system including reagents, equipment and procedures
Daily QC checks the precision of measurements and help identify any deviations or inconsistencies in the analysis procedures . Calibratiors are used to check and verify the accuracy of results produced by machines. To understand what is accuracy and precision you can watch my video on the same topic
