[The stabilization of swine blood for hematologic studies]

Blood samples of 13 sows were preserved with ACD stabilizer with adenine, ACD stabilizer A (DAB) and heparin respectively and were stored in a refrigerator at 4 degrees C over a period of 18 days. During this time the number of erythrocytes and leucocytes, the hematocrit and the hemoglobin concentration were determined 10 times. The best preservation of erythrocytes was observed in ACD stabilizer with adenine. Compared to other stabilizers, preservation of leucocytes was best in ACD stabilizer A. The lysis of the white blood cells follows the exponential function y = ae-bt. ACD-stabilizers permit the preservation of erythrocytes and leukocytes for hematological examinations of swine blood over a period of up to five days.
