Canine blood types are preceded by the letters "DEA". What do these letters stand for?

• A. Detectable Erythrocyte Antibody
• B. Detectable Erythrocyte Antigen
• C. Dog Erythrocyte Antibody
• D. Dog Erythrocyte Antigen

Answer: (D)

The main idea here is how canine blood groups are named and what those letters represent. The acronym DEA stands for Dog Erythrocyte Antigen. “Dog” specifies the species, “Erythrocyte” refers to red blood cells, and “Antigen” is the surface molecule on those cells that can trigger an immune response. This naming is about the markers on red blood cells themselves, not about antibodies or a general detectable feature. In transfusion practice, tests look for these specific antigens (like DEA 1.1, DEA 1.2, etc.) to help ensure donors and recipients are compatible and reduce the risk of transfusion reactions.
