Dear Ohlbe,

» Really ?

Really.

» I usually see only singlets, not duplicates …

That’s risky. If a calibrator at the LLOQ or ULOQ is out of range, you are in trouble.

» (in the past many labs analysed the LLOQ and ULOQ samples in duplicate, with only one of the results being used following an SOP, but all others were singlets).

I see. How does such an SOP look like? Pick out the best?
