Assessment of coagulation before and after packed red blood cell transfusion in dogs using thromboelastography


This study explores the effect that red blood cells and whole blood viscosity (“thickness”) have on a diagnostic technique called Thromboelastography (TEG), so the limitations or biases of the instrument may be better understood and interpreted in a clinical setting.

Inclusion Criteria

  • Canine anemia of any cause requiring non-urgent, non-intraoperative packed red blood cell transfusion in the ICU

Study Design

We would be obtaining blood from dogs with naturally occurring anemia (low red blood cells) that need a transfusion, as is the case with your pet. With enrollment, a small blood sample (<5mL, or about a teaspoon) will be taken from your pet just before the transfusion and again after the transfusion is complete. This blood will be run on the TEG and will also have its viscosity measured.

Client Compensation

  • Any cost associated with tests performed specifically for this study (TEG and blood viscosity) will be covered by the study

Client Cost

  • All other medical treatment costs are to be covered by the client
