Principles of blood transfusion with blood group O

The properties and structures of blood vessels will be disrupted if the blood types are not matched correctly. Our body has the main blood groups including A, B, AB, O. Therefore, the correct identification of blood group and blood donation plays an important role in avoiding the risks of receiving the wrong blood type. to the recipient. This article will help you better understand the special blood types O blood group and the principles of blood transfusion with O blood group.

In the current system of blood groups, they are classified based on the principle of determining the presence of antigenic components on the surface of red blood cells. Red blood cell antigens often bring many health benefits because these antigens have the ability to help the immune system detect foreign antigens entering the body or possibly harmful factors occurring in the body. incompatible transfusions.
Science has now discovered more than 30 blood group systems, but ABO and RH(D) are considered two extremely important blood groups because of the immunogenic properties of this blood group. Blood group O is known as the common blood group in the ABO blood group system. In the Vietnamese population, according to statistics, blood group O accounts for about 42% of the population, and blood group O+ accounts for the majority. Blood group O can donate which of the blood group system? Due to the nature of blood group O, there are no antigens on the surface of red blood cells, so group O can be transfused to people of all four blood types in the ABO blood system and without any reaction when performing a blood transfusion. .
Why blood group O only give but not receive? Since blood group O has no antigens on the surface of red blood cells, it can be transfused to all other blood types. Therefore, blood group O is always prioritized for reserve because it can be used for blood transfusion in case of emergency with unidentified blood group. So, blood group O can receive which blood group in the blood group system? For people with blood type O, it will be very difficult to receive other blood because type O blood is only compatible when being transfused from people with blood type O.
In addition, blood type also has characteristics related to each person's personality. Many studies done to identify problems related to blood transfusion show that blood type has a great influence on the personality as well as health of the owner of that blood type. Although these influence mechanisms have not been studied extensively, they are theoretically recognized by researchers.

In terms of health, people with type O blood do not have antibodies on their red blood cells, so their ability to recognize foreign agents or react against foreign agents is slower. Therefore, people with blood type O are often susceptible to diseases related to infections such as viruses, bacteria, or diseases that can progress to become worse such as cholera, tuberculosis, mumps... or diseases Peptic ulcers caused by HP bacteria are also common in people with blood type O.
People with blood type O may also have a higher risk of cardiovascular disease or cancer compared with people with blood group O. other blood. In contrast, diseases related to cognitive disorders or diseases related to the circulatory system are also less strongly affected by people with blood type O.
O blood group may have little effect on your life, But if you follow a healthy lifestyle, a proper and balanced diet will help people with this blood type prevent diseases and improve the health of the body.

There are many ways to help distinguish O Rh+ and O Rh- blood groups:
Blood test: This method helps determine the surface antibodies of red blood cells to determine the information of O blood group. This method is quite safe. and quickly get accurate results. You can also perform this method when donating blood or treating diseases related to blood type and blood properties. Genetic testing. The blood type in each body is inherited, and the child will definitely have blood type O when both parents have this blood type. If one of the parents has blood type O, a blood test may be needed for accurate results. Saliva test. Antigens on the surface of red blood cells can appear in sweat and salivary glands. The amount of this ingredient accounts for about 80% and if you do a blood test, it can be difficult. So you can do a saliva test to check the accuracy. You use the blood test tool to determine the blood type. Nowadays, there are quite a few home blood test kits available and can be done quickly. To perform this method, it only needs to be based on 1ml of blood sample, then check in such a way, that blood groups of blood group O are left in the air, and will cause the blood to clot. Distinguish two groups of blood group O including O Rh+ and O Rh-. Both belong to blood group O, but the composition of these two blood types has quite different characteristics. Blood group O Rh- belongs to the blood group system with the strongest immunogenic composition of all blood systems other than ABO. Rh rates can depend on race, and Rh- rates are considered rare blood types.
Pregnant women need to take an Rh antigen test, thereby helping to screen and detect the compatibility in the body of the mother and the fetus. If the pregnant mother has Rh - and the fetus is Rh+, then the mother's body can react with the fetal blood. The pregnant woman's body at this time may produce antigens against the Rh + group and cause hemolytic symptoms from mild to severe. In addition, with Rh incompatibility also causes problems in the mother's pregnancies.

The diet is not only reasonable but also made to suit each blood type. However, there is no research to prove that a reasonable diet helps people with blood type O promote better health. In addition, even people with blood type O or other blood types follow some principles to have a good diet including:
The diet should limit sugar and salt content. Sugar helps provide energy for the body, but if you use too much or too little sugar, your blood pressure will not stay in balance. These effects increase the risk of disease. As for the amount of salt in the Vietnamese diet, the actual salt consumption is often higher than the recommended amount. And using a lot of salt is the main cause of edema or high blood pressure .... Therefore, you need to reduce the amount of salt in processing or limit foods with a lot of salt such as melons. salt, cold cuts or chips...
Prioritize diets that include healthy fats. Bad fats can increase the risk of diseases related to metabolic disorders such as blood fat, obesity, and decreased body metabolism. Therefore, you should use healthy fats to help nourish your heart, hair, and cells in a better way. The healthy fats are often found in foods such as: avocado, olive oil, peanut oil, nut oil, or pumpkin seeds, almonds.... contain a lot of monounsaturated fat. As for foods of animal origin, including salmon, mackerel, sardines, herring... contain a lot of polyunsaturated fats.
You should use starches or coarse grains. Whole grains or starches can be rich in antioxidants, fight cancer or sometimes diseases like diabetes, or problems related to heart health. Whole grains or good starches can help keep you fuller for longer, because they are digested slowly and can help stabilize blood sugar better. Hope the above information helps you understand the principle of blood transfusion with blood group O.
