How is calibration and calibration done? Is calibration done with standards? Biochemical testing Medical testing

Yes, calibration with standards, divided into 1-point calibration and N-point calibration, the purpose is to establish a standard curve for the instrument. QC is done with matching QCs, and "matching" means that it is compatible with the instrument, the methodology, and the lot number. Dynamic or static calibration curves and out-of-control rules are used to determine whether the instrument is in control.
