What is golden blood and why is it so rare?

  We all know that some blood types are relatively common, while others are very rare, and some are even so rare that there are not many cases in the world.So, what is the golden blood type?Is golden blood type universal blood?Let's learn together.

  golden blood type

  The golden blood type is RhD negative, commonly known as panda blood, and its RhC, Rhc, RhE, and Rhe are all negative (RhNULL), and there are less than 50 cases in the world.In 1960, the golden blood type was discovered.The odds in the crowd are 1 in 6 million.

  Human blood type is usually determined by antigens composed of certain heritable glycoproteins and sugar chains on the surface of red blood cells.More than 30 blood group systems have been identified.The Rh blood group system is the most complex type of red blood cell blood group system that has been classified. If the red blood cell surface contains the D antigen, it is called RhD positive, otherwise it is called negative.

  Discovery and distribution of Rh blood group

  Andsteinet and Wiener repeatedly injected rhesus monkey erythrocytes into rabbits to make the rabbits produce antibodies against rhesus monkey erythrocytes, and then mixed the rabbit serum containing this antibody with human erythrocytes , found that about 85% of the red blood cells of Caucasians can be agglutinated by this serum, indicating that these people's red blood cells have the same antigen as rhesus monkey red blood cells, so this blood type is called Rh positive blood type; About 15% of people's red blood cells are not agglutinated by this serum, known as Rh negative blood type.This blood group system is called the Rh blood group system.Among all ethnic groups in my country, about 99% of the Han nationality and most ethnic minorities are Rh-positive, and only about 1% are Rh-negative.

  Antigen and typing of Rh blood group system

  The Rh blood group system is the most complex system of red blood cell types.More than 40 kinds of Rh antigens (also known as Rh factors) have been found, among which five are D, E, C, c, and e that are closely related to clinical practice.Theoretically, there are 3 pairs of alleles, C and c, D and d, and E and e, that control 6 antigens.

  The characteristics and clinical significance of Rh blood group are different from the ABO system

  Human serum does not have anti-Rh natural antibodies. Only when Rh-negative people receive Rh-positive blood, will they produce anti-Rh immune antibodies through humoral immunity. Anti-Rh antibodies in serum 2 to 4 months after blood transfusion Antibody levels peaked.

  Is golden blood type universal blood?

  In daily life, what people call "universal blood" refers to type O blood.Therefore, it is considered that type O blood is "universal blood" because there are no A and B antigens on the red blood cells of type O blood.Therefore, in clinical practice, "washed red blood cells" of type O blood are often used for blood transfusions in patients with blood types A, B, and AB.However, this concept is very incorrect. "Omnipotent blood" is not actually "omnipotent", and it is also very dangerous.The plasma of type O blood contains anti-A and anti-B antibodies. Once the plasma of type O blood is transfused into the body of patients with blood types A, B, and AB, agglutination reaction will occur immediately, which will severely damage the recipient's red blood cells and cause hemolysis. .Therefore, transfusion of O-type blood plasma to recipients of other blood types is prohibited.

  "Panda blood" refers to Rh-negative people in the Rh blood group.Neonatal Rh hemolysis is a hemolytic disease caused by the incompatibility of maternal and fetal blood types.Any parent with "panda blood" should receive medical guidance before pregnancy to prevent the occurrence of neonatal hemolysis.
