The agreement between PCV as measured by centrifugation and HCT as measured by the i-STAT 1, as well as osmolality measured by freezing-point depression and calculated osmolality, were assessed via Bland-Altman plot.
Within the next 5 days, plasma samples were thawed, and plasma osmolality was measured in duplicate from the same cryogenic vial by use of a commercial freezing-point depression osmometer (Osmette, Precision Systems, Natick, MA, USA).
