CPT® Code 86860

The CPT® Code 86860 refers to the procedure known as antibody elution, specifically focusing on red blood cells (RBCs). This laboratory test is crucial for measuring the elution of antibodies from RBCs, which can be significant in various clinical scenarios. The test is typically ordered following an antibody screening that reveals the presence of IgG antibodies and/or complement fragments, which are direct anti-globulins that attach to the surface of RBCs. The presence of these antibodies is clinically important as they can lead to transfusion reactions, which may pose serious risks to patients receiving blood transfusions. Additionally, these antibodies can contribute to hemolytic disease in newborns, a condition where the mother's immune system attacks the red blood cells of the fetus or newborn. The antibody elution test serves to identify specific antibodies present in the blood, thereby assisting healthcare providers in selecting the most compatible blood products for transfusion. This is particularly vital in ensuring patient safety and minimizing the risk of adverse reactions during transfusions. Furthermore, the elution test may be ordered after a transfusion reaction has occurred, allowing for the identification of the antibodies responsible for the reaction. The procedure involves obtaining a blood sample, which is typically done through a separately reportable venipuncture. The testing of whole blood is conducted using a method known as hemagglutination, which helps in determining the presence and type of antibodies that have eluted from the RBCs.
