Detailed explanation-1: -Acute immune hemolytic reaction It happens when donor and patient blood types do not match. The patient’s antibodies attack the transfused red blood cells, causing them to break open (hemolyze) and release harmful substances into the bloodstream.
Detailed explanation-2: -For example, if someone with Type O blood (blood with no A or B antigens on the surface of red blood cells) received red blood cells donated from someone with Type B blood (blood containing B antigens), the recipient’s immune system would immediately identify the new blood cells as foreign and seek to destroy them.
Detailed explanation-3: -The correct option is A O, Rh-A man whose blood groups in not known meets with a serious accident and needs blood transfusion immediately. Which one of the blood groups mentioned below are readily available in the hospital will be safe for transfusion? Q.
Detailed explanation-4: -Type O patients have naturally occurring anti-A and anti-B antibodies in their blood. A type O patient would immediately react to the type A or type B blood being transfused into them. The ABO system is very antigenic and this transfusion would cause a very strong immune response. This response could be fatal.
