Dear Ohlbe,

» Most frequent: use the first result only. If, and only if it fails (more than 20% deviation at the LLOQ, 15% at the ULOQ): exclude it and use the second. The aim being of course to avoid having to truncate the curve in case of failure.

» I see this less and less often. Not sure why (guess: some FDA inspectors did not like it).

Count me in. If you analyzed duplicates, use them.

I believe there is no philosophical high-road in science,
with epistemological signposts. No, we are in a jungle
and find our way by trial and error,
building our road behind us as we proceed.    Max Born
