An unconscious patient is rushed into the emergency room and needs a fast blood transfusion. Because there is no time to check her medical history or determine her blood type, which type of blood should you, as her doctor, give her?
- A

Without knowing a patient’s blood type, the only type of transfusion that we can safely give is O-. People with O- blood are considered universal donors because their blood cells contain no surface antigens. Therefore, O- blood can be given to anyone without causing potentially life threatening consequences.
People with AB- blood group are not considered universal donors
People with AB+ blood group are not considered universal donors
People with O+ blood group are not considered universal donors
