Each sample was separated in 2 aliquots, of which one was stored in ambient temperature (25 ˚C) and the other one was refrigerated (2 to 4 ˚C). Complete blood counts were performed in 1, 2.5, 5, 12, 24, 36 and 60 hr post-sampling for each aliquot of every sample using a flow cytometer. Packed cell volume values remained stable in the samples kept in room temperature (RT), whereas a significant increase was noted in the refrigerated ones 24 hr post-sampling. Statistically significant increases in red blood cell counts were noted after 24hr in the samples stored in 2 to 4 ˚C and after 12 hr in those kept in RT. No significant changes were observed in haemoglobin concentration. A significant decrease was evident only 60 hr post-sampling for the white blood cells kept in RT, but not for those kept in 2 to 4 ˚C. Platelet counts significantly decreased after 24 hr in the refrigerated aliquots and after 5 hr in those kept in RT. The results of this study indicate that storage of blood samples for up to 24 hr in 2 to 4 ˚C is associated with the least artifactual changes.}, keywords = {Complete blood count,Dog,Hematology,stability,Temperature}, url = {https://vrf.iranjournals.ir/article_22160.html}, eprint = {https://vrf.iranjournals.ir/article_22160_c5650ab8516d58cb7f71d6ced7612c59.pdf} }
