General information about the test:
Testing is for DEA 1.1. A universal donor should be DEA 1.1 negative. Dogs have 8 standard blood groups (DEA system: 1.1, 1.2, 3, 4, 5, 6, 7, and 8) 1.1, 1.2 and 7 are the most important antigens in transfusion medicine. Universal donors should be negative for all 3 antigens and must definitely be negative for 1.1.
DEA 1.1 antibody causes an acute haemolytic reaction. DEA antibodies to 1.2 and 3 cause a more chronic immune reaction with shortened RBC life span and no systemic signs. Potential donor dogs should be clinically healthy and on no medication at time of testing.
