Assessing positive pretransfusion antibody screens, transfusion reactions, hemolytic disease of the newborn, and autoimmune hemolytic anemias
This test is not useful for monitoring the efficacy of Rh-immune globulin administration.
This test is not useful for identifying antibodies detected only at 4 degrees C or only after extended room temperature incubation.

The following tests may be ordered and performed as needed for antibody identification: direct antiglobulin testing (polyspecific), including its reflex tests and special red cell antigen typing. Additional reflex charges will be added as needed for antibody elution, antibody adsorption, antibody panels, and special red cell antigen typings.
If certain antibodies are detected and the patient is known to be pregnant, an antibody titration will be performed at an additional charge.

After exposure to foreign red blood cells (RBC) via transfusion or pregnancy, some people form antibodies that are capable of the destruction of transfused RBC or of fetal RBC in utero. It is important to identify the antibody specificity in order to assess the antibody's capability of causing clinical harm and, if necessary, to avoid the antigen on transfused RBC.
Autoantibodies react against the patient's own RBC as well as the majority of cells tested. Autoantibodies can be clinically benign or can hemolyze the patient's own RBC, such as in cold agglutinin disease or autoimmune hemolytic anemia.
Negative,
If positive, antibodies will be identified and corresponding special red cell antigen typing on patient’s red blood cells will be performed.
Specificity of alloantibodies will be stated.
The patient's red blood cells will be typed for absence of the corresponding antigens or as an aid to identification in complex cases.
A consultation service is offered, at no charge, regarding the clinical relevance of red cell antibodies.
Recent administration of Rh-immune globulin may cause anti-D to be identified and appear falsely as an alloantibody.

A panel of reagent type O erythrocytes, with known antigenic determinants and the patient's cells are tested with the patient's serum/plasma. This panel should yield a distinct pattern of agglutination or hemolysis that identifies the auto- or alloantibody specificity. Elution, absorption, neutralization, and other special techniques may be necessary to complete antibody identification.(Fung MK, Eder AF, Spitalnik SL, Westhoff CM. Technical Manual. 19th ed. AABB; 2017)
