Introduction
People with blood type AB can only receive blood transfusions from individuals with type AB blood. Currently, in clinical practice, the principle of blood transfusion is to transfuse the same blood type. The reason for using the same blood type is that when red blood cells containing agglutinogen A or agglutinogen B are mixed with serum containing anti-A agglutinin or anti-B agglutinin, the corresponding opposing agglutinogens and agglutinins interact, causing the red blood cells to clump together.
Some people have blood type AB, which is considered a universal recipient. So, to which blood types can AB-type blood be donated?

AB-type blood can only be transfused to individuals with AB blood type. Currently, in clinical practice, the principle of blood transfusion is to transfuse the same blood type. The reason for using the same blood type is that when red blood cells containing agglutinogen A or agglutinogen B are mixed with serum containing anti-A agglutinin or anti-B agglutinin, the corresponding opposing agglutinogens and agglutinins interact, causing red blood cells to clump together.
These clumped red blood cells can block small blood vessels, disrupting normal blood circulation, leading to hemolysis (rupture of red blood cells) and the release of large amounts of hemoglobin. When substantial hemoglobin is excreted through the kidneys, it may block renal tubules, damage kidney function, and result in oliguria (reduced urine output) or anuria (absence of urine). This can cause symptoms such as numbness in limbs, body tremors, chills, chest tightness, back and waist pain, rapid heartbeat, and low blood pressure, potentially leading to death in severe cases.
Therefore, careful selection of compatible blood types is essential during transfusion. After receiving a blood transfusion, it's important to enhance nutrition by consuming more lean meat, milk, and other nutritious foods to promote recovery. Adequate rest and sufficient sleep are also crucial. We hope this answer has been helpful to you. Wishing you good health and happiness!
