Clinical Information

This ABO and Rh blood typing test identifies the presence of specific red cell antigens and antibodies to determine the ABO/Rh type.

Reference Values

ABO and Rh blood group antigens identified

Interpretation

Standard ABO/Rh type will be reported. Routine types include: O pos, O neg, A pos, A neg, B pos, B neg, AB pos and AB neg. Any relevant discrepancies will be noted.

Cautions

Clinical evaluation of antibodies identified is necessary to determine their potential for harm to the patient at this time and to assess appropriate action to be taken in the future.

Method Description

Agglutination of patient red cells with an antiserum represents the presence of the corresponding antigen on the red cells. Agglutination of patient plasma with reagent red blood cells represents the presence of the corresponding antibodies.(Cohn CS, Delaney DO, Johnson ST, Katz LM, Schwartz J, eds. Technical Manual. 21st ed. AABB; 2023)
