What is the best blood type

blood types

The blood groups were discovered by the Austrian scientist Karl Landsteiner in 1901. It was found that the blood type or group of the individual is determined by the genetic genes that are transmitted to him from the parents, and what distinguishes the individual’s blood from others is the presence of a certain mixture Of the protein molecules known as antigens and antibodies, ^{[1] and} in fact there are two main systems for classifying blood groups and groups, namely; The ABO system, and the RH factor system, to produce together eight different blood groups; Each blood group contains its own antigens that are found on the surface of red blood cells, ^[2] while it contains antibodies inside the blood plasma , ^[1]It is worth noting that the ABO system divides the blood groups into four groups: A, B, O, and AB, based on the presence or absence of A and B antigens, while the Rhesus factor system further divides these groups. Negative and positive based on the presence of the RH antigen. Thus, the eight blood groups are represented as follows: ^[3]

• Blood type-O: does not contain any A, B, or RH antigens.
• Blood type + O: containing the RH antigen only.
• Blood type-A: which contains antigen A.
• Blood type A +: contains A antigen and RH antigen.
• Blood Type-B: contains the B antigen .
• Blood type B +: contains the B antigen, and the RH antigen.
• Blood type- A, which contains A and B antigens.
• Blood type AB +: which contains all A, B and RH antigens.

Best blood type

O blood group is the best blood group of all blood groups in terms of donating blood; This is because the owners of this type can safely donate blood to any other individual, regardless of the type of blood type, whether by the ABO system or the Rhesus factor system. Whereas, the red blood cells belonging to blood type O do not have any A, B, or RH antigens on their surface, and this makes the blood of the donor with blood group -O compatible with all other factions, and accordingly it is called the general donor , ^[4] It should be noted that there is a group of studies that were conducted during the past years on blood groups, and showed a strong potential for blood group associationRisk of exposure to certain diseases and health problems; Where studies have found that people with blood type O are less at risk of developing coronary heart disease , and also indicated that people with blood type O are less at risk of developing health problems associated with the formation of clots in blood vessels. Such as: deep vein thrombosis , and pulmonary embolism , in addition to the reduced risk of developing some types of cancer in people with blood type O, the most prominent of which are; Stomach cancer , pancreatic cancer, and ovarian cancer , as for memory diseases and the problem of dementiaHowever, people with blood type O are also fortunate to have a lower risk of developing these problems, according to some studies. ^[5]

The importance of knowing blood type

The importance of taking a blood type test, and knowing it, lies in the following: ^[5]

• Directing the individual to eat appropriate foods: Some diets based on blood type have appeared recently , which are believed to contribute to maintaining the health of the individual, by motivating the individual to eat some types of food and avoid others based on his blood type. Assuming that the types of food interact chemically with the blood type, and in the event that the individual adheres to a diet commensurate with his blood type, this increases the efficiency of his food digestion, the amount of energy in the body, also stimulates weight loss, enhances the individual's ability to withstand stress, and increases clarity Mind, and reduces the risk of disease, and although many people who follow these diets felt improved health, these diets need more studies to prove their effectiveness further.
• Determining risk factors for disease: Some studies have noted a relationship between blood type and a higher risk of developing certain diseases and problems. Some studies have shown a higher risk of coronary heart disease in people with blood type AB , and that people who have blood type AB are more likely to have memory problems that may lead to dementia, and people with type A blood are more at risk of stomach cancer, while the risk of infection increases. With kidney cancer and skin cancer in people with blood type O, and here it should be noted that the increased risk of some diseases related to the blood type, according to the results of these studies, does not necessarily mean that these diseases are infected, but the individual should benefit from knowing his risk factors to prevent infection With these diseases, early detection and treatment in the event of infection.
• Ensure that the blood group of the pregnant woman is compatible with her fetus: The problem of incompatibility of the pregnant woman’s blood type with the fetus is when the pregnant’s blood type is negative, while the fetus’s blood group inside her gut is positive - that is, it contains the antigen RH - Antibodies to the antigen, RH, when a miscarriage occurs or the placenta ruptures at the time of birth, and it should be noted that these antibodies do not affect the first child, but rather the second child if he has a positive blood type as well. The antibodies to the RH antigen enter the placenta and cause the fetus to develop a severe form of anemia at birth. Therefore, if the husband’s blood group is positive, a pregnant woman with a negative blood group is given immunoglobulin during weeks 28-32 of pregnancy and at birth; To prevent the formation of antibodies in the mother's body. ^{[6] [7]}
• Checking the compatibility of blood groups when transfusing blood or organs: Some patients need a blood transfusion or an organ transplant sometimes, and this requires the provision of a donor of the same blood type according to the ABO system and the Rize factor system, and in the absence of a completely identical type, as in emergency cases So, it is possible to rely on a blood type that matches or harmonizes with the patient’s blood group, so that the immune system does not build upOf the patient to attack the blood transfused to him; For example, a patient with blood type AB can receive blood from all other blood groups (A, B, and O), so he is called a general recipient or recipient, and a patient with blood type A can receive blood from type A or O, as well as For a patient with blood type B receiving blood of type B or O, and it is worth noting that the patient’s failure to obtain a blood type corresponding to his blood type exposes his life to a great risk that may reach death. Whereas, the antibodies of the patient's immune system attack any substance that is not recognized, whether it is a bacterium , a virus , or even antigens that are not present in his blood, and the destruction and destruction of these generators results in serious and life-threatening medical conditions. ^{[4] [8]}
