Alloimmunization in dogs after transfusion: A serial cross-match study.

Background: Cross-matching is performed to determine the serological compatibility of donor and recipient blood. Current guidelines recommend that cross-matching should be performed in dogs when an initial transfusion was performed more than 4 days ago or when the transfusion history is unknown.

Hypothesis: Determination at what time point alloantibodies are detected in dogs after transfusion.
