Effect of cross-match on packed cell volume after transfusion of packed red blood cells in transfusion-naïve anemic cats.

Background: Novel feline RBC antigens might contribute to decreased efficacy of RBC transfusion and increased incidence of acute transfusion reactions (ATR).

Objectives: To examine the effect of major cross-match in transfusion-naïve anemic cats on the incidence of acute immunologic transfusion reaction and transfusion efficacy for up to 24 hours after transfusion.

Animals: Forty-eight client owned transfusion-naïve anemic cats.
