 CROSS MATCHING PROCEDURE Types, Purpose, Principle, Procedure and Interpretation Cross Matching is a procedure performed prior to a blood transfusion to determine whether donor blood is compatible (or incompatible) with recipient blood. Compatibility is determined through matching of different blood group systems, the most important of which are the ABO and Rh system, and/or by directly testing for the presence of antibodies against a sample of donor tissues or blood. Purpose of Cross Matching The crossmatch is routinely used as the final step of pretransfusion compatibility testing. The purposes of compatibility testing are to detect: irregular antibodies; errors in ABO grouping, and clerical errors in patient identification and result recording. The crossmatch will detect the following: 1. Most recipient antibodies directed against antigens on the donor red blood cells. 2. Major errors in ABO grouping, labeling, and identification of donors and recipients. Principle Cross-matchi...
