How does a calibrator differ from a control material?Group of answer choicesA calibrator is used to verify if the results from the previous run are within the acceptable limitsA calibrator is used to set the instrumentA control is used to set the instrumentA calibrator is used to assess within-run imprecision
Solution
A calibrator and a control material are both used in laboratory testing, but they serve different purposes.
A calibrator is used to set the instrument. This means that it helps to ensure that the instrument is giving accurate readings. It does this by providing a known value that the instrument should read. If the instrument does not give this reading, then it may need to be adjusted or calibrated.
On the other hand, a control material is used to verify if the results from the previous run are within the acceptable limits. This means that it helps to ensure that the testing process is working correctly. It does this by providing a sample that should give a certain result. If the result is not within the expected range, then there may be a problem with the testing process.
Therefore, the correct answer is: A calibrator is used to set the instrument.
