Dear Auditor!

❝ […] if we are taking duplicates (LLOQ & ULOQ) then we should consider both the duplicates (10 no. of samples) or mean of duplicates (LLOQ & ULOQ) for plotting?

Don’t plot means of duplicates (loss of visual information about their variability). Plot all data points you have used in the calibration, regardless whether you have used all n=10, dropped one (n=9), or two (n=8). Overlay the calibration curve based on the estimated slope and intercept.
