Method Comparison with Human Whole Blood Samples

For testing syringe and capillary modes, blood was collected in heparinized
vacuum tubes. It was tonometered at 37°C and/or adjusted chemically. Several
levels of tHb were prepared by separating the red cells from the plasma and
recombining appropriately. Specimens were assayed on Rapidlab 1240 and
Rapidlab 865 systems.
