COLA accredits Immunohematology/Transfusion Services to ensure safe and quality blood banking practices. This area covers ABO/Rh typing, compatibility testing, antibody screening, crossmatching, donor screening, component labeling and storage, and transfusion reaction monitoring. Accreditation assesses the lab’s quality management system, standard operating procedures, personnel qualifications, proficiency testing, and corrective-action processes, all aimed at protecting patients who receive blood products. The other options describe techniques or departments that operate in different areas of a laboratory or hospital and are not the specific transfusion-service domain COLA accredits.
