Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

After exposure to foreign red blood cells (RBCs) via transfusion or pregnancy, some people form antibodies that are capable of the destruction of transfused RBCs or of fetal RBCs in utero. It is important to identify the antibody specificity to assess the antibody's capability of causing clinical harm and, if necessary, to avoid the antigen on transfused RBCs.

 

Autoantibodies react against the patient's own RBCs as well as the majority of cells tested. Autoantibodies can be clinically benign or can hemolyze the patient's own RBCs, such as in cold agglutinin disease or autoimmune hemolytic anemia.

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Negative

If positive, antibodies will be identified and corresponding special red cell antigen typing on patient’s red blood cells will be performed.

Interpretation
Provides information to assist in interpretation of the test results

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.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Recent administration of Rh-immune globulin may cause anti-D to be identified and appear falsely as an alloantibody.

Method Description
Describes how the test is performed and provides a method-specific reference

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.(Cohn CS, Delaney M, Johnson ST, Katz LM, Schwartz J. eds: Technical Manual. 21st ed. AABB; 2023)
