A bleeding patient requires red cells before pretransfusion testing is complete. What is the best laboratory practice?

• 1 Delay all blood until the antibody identification is final regardless of clinical urgency, even if the patient is hemodynamically unstable and actively bleeding, as per standard protocol for elective transfusions
• 2 Issue an ABO-incompatible unit selected at random without any serological testing or physician consent, ignoring the patient's ABO type and relying on guesswork
• 3 Follow the emergency-release policy, document authorization, issue appropriate uncrossmatched blood, and complete testing as soon as possible ✓ 정답
• 4 Skip patient identification because the situation is urgent and rely solely on the nurse's verbal report of blood type without any verification
