How to correct calibration coefficients with QC values

The operation of QC is slightly different according to different instruments, most of the instruments have QC menu, the instrument will be well maintained according to the prompts to do the same operation as the specimen, the instrument will automatically identify the CV and print out the report, the instrument does not have this function needs to be operated in the same way as the normal specimen test, and each QC is generally tested more than 6 times to calculate the report. Calibration is carried out in the CALIBRATION menu, which is available in every instrument, the instrument will be well maintained, in accordance with the prompts to the specimen test the same operation can be, generally at least three times up to 12 times, or more than 5 times is good, so that the instrument is automatically calculated to correct the coefficient of the need to correct the instrument for correction regardless of whether it is a quality control or calibration of the test material should be mixed well. The CV range of quality control is large, as long as the results are within the range is not out of control, but the range of calibration is very small, so try to correct on the target value, so as to ensure quality control.
