Therefore, they are considered clinically significant, but the relationship between detection and pathologic effect is not well defined. The presence of these autoantibodies complicates pretransfusion and compatibility testing by panreactivity that precludes detection of underlying alloantibodies by routine testing.

Immunologic compatibility of the blood was confirmed with sera from potential recipient sheep using a saline agglutination crossmatch. Following confirmation of compatibility, 2 units of PRBC were transfused into each recipient sheep (n=12). Results: Methods for collection, processing, crossmatching and transfusion of sheep blood were established.

What is crossmatching? The crossmatch is a direct test between your white blood cells and a blood sample from the patient. This is a test of whether the patient has any antibodies in their blood that could attack the transplanted organ and cause it to fail. A transplant cannot take place unless the result of this test shows that none of these

The crossmatch is a direct test between antibodies in your blood and white blood cells from a possible donor. This is the ultimate test of whether you have any antibodies that could cause a transplant to fail. In some cases, the transplant will not go ahead until we carry out this test and reported to the Transplant Team.
