ESTIMATION OF HYPOXIC CONDITIONS IN CALVE S USING THE ERYTHROCYTE DENSITY SEPARATION TEST

The erythrocyte density separation test (EDT) divides the red blood ce lls into two groups: younger (less dense) and older (more dense) eryth rocytes. Using this test enables veterinarians to assess the erythropo iesis in calves on the basis of the percentage of less dense (younger) . red blood cells. Anemic calves, as well as those with pneumonic infe ctions show higher proportions of less dense red blood cells in the ED T than healthy ones. This testing procedure makes it possible to estim ate the effects of an oxygen deficiency condition, such as hypoxemia, anemia, shock etc. on the peripheral tissues. So the EDT represents a valuable complement to existing hematological laboratory methods. Carr ying out the EDT is very simple and suitable in routine clinical testi ng.
