Blood Typing in Dogs
Dog blood groups are classied using the Dog Eryth-
rocyte Antigen (DEA) system. The DEA system denes
six blood types based on the presence of specic in-
herited antigens on the surface of the red blood cells.
In the context of transfusion DEA 1 is the most im-
portant blood type because transfusion with DEA 1
positive blood to a negative recipient can cause sensi-
tization or severe heamolytic reactions.
The Element COAG™ DEA 1 Blood Typing Test uses
antibodies specic to the DEA 1 antigens to deter-
mine the amount of DEA 1 antigens on the blood cells
in a sample.

ing test is shown below
DEA 1 Negative
Safe Blood Donation
Dogs that have been tested positive for DEA 1
can be transfused with blood from any donor
without risk of sensitization or hemolytic reac-
tions. Blood from DEA 1 positive donors can only
be donated to DEA 1 positive recipient dogs.
Dogs that are dicult to type due to antigen
properties should only be transfused with blood
from DEA 1 negative donors. Blood from dogs
in this group should only be donated to DEA 1
positive recipient dogs.
To avoid sensitization or hemolytic transfusion
reactions DEA 1 negative dogs should only be
transfused with blood from DEA 1 negative
donors. Dogs that have been tested negative for
DEA 1 are suitable donors for any other dog.
The Element COAG™ DEA 1 Blood Typing Test is a joint development of dmslaboratories,
