Coagulation disorders represent a common diagnostic challenge in veterinary medicine. The objective of this study was to establish reference intervals for EXTEM and INTEM test parameters using ROTEM® delta in healthy canines, in order to facilitate the clinical interpretation of viscoelastic tests in this species. Thirty clinically healthy dogs, older than one year, were studied and underwent ROTEM® delta testing in the EXTEM and INTEM channels, analyzing parameters such as Clotting time (CT), Clot formation time (CFT), alpha angle, Amplitude at 10 minutes (A10), Amplitude at 20 minutes (A20), Clot firmness (CFF), and Lysis at 30 minutes (LI30). The reference intervals obtained were consistent between animals and comparable to those reported internationally, with some variations attributable to regional factors. This study provides the first reference values in Argentina for ROTEM® delta in canines, constituting a useful tool for the diagnosis and management of hemostatic disorders in the clinical setting.
