In fact, the problem of rh negative O blood type is not complicated, but many friends do not know the difference between RH negative O blood type and positive O blood type. Therefore, , today the editor will share with you some knowledge about rh-negative O blood type. I hope it can help you. Let’s take a look at the analysis of this problem together!

1. What is type O blood?
Type O blood is a universal blood type that can receive indiscriminate blood transfusions from type O blood. , but blood can only be donated to people who also have type O blood. Since type O blood has no A or B antigens, it is also called the \”antigen-free blood type\”, which means that it is relatively flexible in matching types.
2. Full name of blood type O
1. Blood type O It is a common blood type, which refers to a blood type that contains neither A antigen nor B antigen in the blood. It is called a \”universal blood transfusion recipient\”.
2. Type O blood means that there are no A or B type antigens on the surface of human red blood cells. Their sera produced antibodies to both antigens. Therefore, if the antibodies in the donor\’s blood are separated before receiving blood, people with type O blood are \”universally suitable blood donors.\” However, they can only accept blood from the same blood type, for example, a person with type O can only receive blood from type O. Basically, type O is the most common blood type in the world.
3. The earliest blood group system recognized by humans is the ABO blood group system. In 1900, Karl Landsteiner of the Institute of Pathology of the University of Vienna in Austria discovered that the serum of healthy people had an agglutination effect on the red blood cells of different human individuals. If serum and red blood cells taken from different people are mixed in pairs, they can be divided into three groups: A, B, and C (later renamed O). Later, his students Decastello and Sturli discovered a fourth group, Group AB.
4. A few years later,Landsteiner and others discovered other independent blood group systems, such as the MNS blood group system, Rh blood group system, etc. In 1930, Landsteiner won the Nobel Prize in Physiology or Medicine.
5. Over the past few decades, new blood group systems have been continuously reported, and the International Blood Transfusion Society, established in 1935, is responsible for identification and naming. The 30 recognized human blood group systems include more than 600 antigens, most of which are very rare.
6. The discovery of blood types has created emerging disciplines such as immunohematology and immunogenetics, which are of great significance to clinical blood transfusion work. The blood group system was also widely used in forensic medicine and paternity testing, but has been gradually replaced by more precise genetic methods.
3. Composition of type O blood
1. Type O Bloody people refer to people who have neither A nor B antigens on their red blood cell membranes. Only when the child inherits chromosomes that have no antigens from both men and women will type O blood be formed. For example, if the father has blood type A and the mother has blood type B. Then one of the father\’s chromosome arms will carry the a antigen and one without the antigen, and one of the mother\’s chromosome arms will carry the b antigen and one without the antigen. When two chromosome arms without antigens combine, the child will have type O blood.
2. Type O blood is only on the surface of red blood cells and contains neither A nor B antigens. It is commonly known as universal blood transfusion. However, because plasma contains anti-A and anti-B antibodies, it may cause the recipient to have varying degrees of red blood cell hemolysis. Therefore, type O blood cannot be randomly transfused to other people. Rh-positive blood of blood type O cannot be transfused into any RH-negative blood type, and only a small amount can be transfused into any RH-positive blood type. However, people with type O blood cannot receive blood transfusions from other blood types, as this may cause hemolytic reactions.
4. What is the difference between RH-negative O blood and positive O-type blood
The difference lies in the preciousness of blood types. RH-negative blood is what we usually call panda blood. At the same time, if you want to keep diseases away from you, my suggestion is to start with your daily life. You should eat in moderation, eat more whole grains and less raw, cold and spicy food. At the same time, you should maintain good exercise habits and exercise every day. Another thing is to maintain a good attitude.
OK, about rh-negative blood type O and RThis concludes the content on what is the difference between H-negative O blood and positive O blood. I hope it will be helpful to everyone.
