title: [Evaluation of hypoxic conditions in calves using the erythrocyte density test (EDT)].
abstract: The erythrocyte density separation test (EDT) divides the red blood cells into two groups: younger (less dense) and older (more dense) erythrocytes. Using this test enables veterinarians to assess the erythropoiesis in calves on the basis of the percentage of less dense (younger) red blood cells. Anemic calves, as well as those with pneumonic infections show higher proportions of less dense red blood cells in the EDT than healthy ones. This testing procedure makes it possible to estimate 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. Carrying out the EDT is very simple and suitable in routine clinical testing.
