40 mM HEPES pH 7.4, 10 mM NaCl, 150 mM KCl, 2.5 mM MgCl 2) with the appropriate amount of [3 H]-labelled arginine and cold arginine. At the end of one hour, the beads were aspirated dry ...

The smallest response was a rise from 1.5 to 8 mμg. per milliliter. In no subject did arginine fail to cause ... the arterial-blood pH is not greatly altered, 6 and no subjective discomfort ...

The primary outcome was the overall diagnostic accuracy according to prespecified copeptin cutoff values of 3.8 pmol per liter after 60 minutes for arginine and 4.9 pmol per liter once the sodium ...
