少量的草酸钾可能对血液粘度没有影响，迄今为止归因于它的变化可以归因于二氧化碳含量的变化或红细胞的沉降。血液暴露在空气中时粘度迅速增加。这种变化伴随着二氧化碳的损失，可以通过加塞容器并搅拌直到血液与其上方的空气达到二氧化碳平衡来防止，此时粘度保持恒定。在测定血液粘度时，红细胞应均匀地悬浮在整个血浆中。这可以通过旋转5至10 cc来实现。在分液漏斗中滴入100毫升血液1分钟。
Small amounts of potassium oxalate probably have no effect on the viscosity of the blood and changes hitherto ascribed to it can be attributed either to variation in carbon dioxide content or to sedimentation of the red blood cells. The viscosity of blood when exposed to the air increases rapidly. This change accompanies a loss of carbon dioxide and can be prevented by stoppering the container and agitating until the blood comes into carbon dioxide equilibrium with the air above it, when the viscosity remains constant. It is essential in determining the viscosity of blood that the red cells should be uniformly suspended throughout the plasma. This can be accomplished by rotating 5 to 10 cc. of blood in a separating funnel for 1 minute.
