Blood Transfusion: Life-Saving Therapy and How Korea Ensures Blood Safety

Blood transfusion involves the intravenous transfer of blood or blood components from a donor to a recipient. It is a critical medical intervention used in surgery, trauma, severe anaemia, haematological disorders (leukaemia and other blood cancers), and obstetric emergencies. Modern transfusion medicine uses component therapy — red blood cells, platelets, fresh frozen plasma (FFP), and cryoprecipitate — allowing precise treatment of specific deficiencies rather than whole blood transfusion.

Blood safety in Korea is managed by the Korean Red Cross Blood Services, which collects the large majority of the national blood supply and maintains rigorous testing of all donated blood — screening for HIV, Hepatitis B and C, syphilis, and other pathogens. Korea's blood supply is among the safest in the world. All blood is grouped and cross-matched to the recipient's blood type before transfusion. Electronic compatibility testing systems reduce the risk of ABO incompatibility — the most serious transfusion reaction.

Blood donation in Korea is voluntary and unpaid, coordinated through the Korean Red Cross Blood Services. Despite a strong donation culture, Korea — like many rapidly ageing societies — faces recurring blood supply shortages, particularly around major holidays (Chuseok, Seollal) and exam periods, when university students (historically a major donor group) are less available. Blood type O-negative is always in particular demand. Donors must typically be 16–69 years old (with additional screening for first-time donors over 65), weigh over 50kg, and be in good health. Blood can be donated at Red Cross blood donation centres, mobile donation buses, or blood donation drives held at universities, workplaces, and public venues nationwide.
