[Comparative studies with various anticoagulant stabilizer combinations for the preservation of blood specimen in leukosis diagnosis. 1. Studies on storage life of dry-preserved blood vials for the hematologic diagnosis of leukosis]

Four anticoagulants in current use were compared in blood samples used to prepare dried specimens. The most suitable was a mixture of one part of heparin solution (5000 IU strength) and four parts of distilled water. Blood samples treated in this way must be process at the laboratory within 16 hours. Specimens dried in tubes could be stored for a long time, and this was the best way of dealing with samples from individual or export cattle.
