Abstract excerpt

BACKGROUND AND OBJECTIVES: Alloantibodies against high-prevalence antigens can create significant barriers to transfusion, particularly in patients with complex medical needs. Serological investigations include use of enzyme-treated red cells and dithiothreitol (DTT) testing, which can enhance or diminish antibody reactivity, providing insight into potential antibody specificity. Additionally, molecular testing...
