Recovery and Precision with Whole Blood
For testing syringe and capillary modes, blood was collected in heparinized vacuum
tubes. It was tonometered at 37
°
C and/or adjusted chemically. Three levels of tHb
were prepared by separating the red cells from the plasma and recombining
appropriately. For each run, three replicates of each level were run on four 800
systems.
Table E-44 through Table E-46 summarize the results of the 800 CO-ox module
recovery and precision testing.
