Calibration and QC point with same concentration [Bioanalytics]
Dear Relaxation,
The LQC sample has to have a concentration of maximum 3 times the LLOQ, and it is in the lab's interest to have it close to 3 times (lower variability than e.g. 2 times, less chances to fail). You don't necessarily have a calibration sample at the same level of concentration.
Same for the HQC. You don't necessarily have a calibration sample in the desired zone.
It is actually only for the MQC that you could easily have the same concentration. But then, may I turn the question back: why would you want it to be at the same level of concentration as a calibration sample ?
❝ And why would it be common sense, that they should be different, as long as I do not use the same stock solution?
