In humans, blood groups are divided into many types and each type has its own characteristics. If the blood group is not properly transfused, it can disrupt the structure of the blood vessels, endangering the life of the person receiving the blood. The following article will help you better understand the characteristics of blood groups and how to classify them.

You may have heard of the four basic blood types: A, AB, B, and O, and the positive or negative variations of these blood types. But did you know that these four types can be divided into many different blood types?

Most of us know that the common blood types include A, B, AB, O. Each blood type has a plus and minus blood group system. Each person is born with genetic inheritance from their father and mother, so they have 1 of the 8 blood group systems listed above and it does not change throughout life.

Frozen red blood cells are a very special type of red blood cell preparation. With harsh freezing conditions, storage time will increase significantly, frozen red blood cells will play a key role, contributing to the effectiveness of treatment for patients, especially in cases requiring rare blood transfusions.

Blood type is one of the biological characteristics of humans, determined by genes, currently people have recorded about 36 blood types. In terms of application in medical facilities, the two most used blood group systems are ABO and Rh. The ABO blood group system includes four blood groups A, B, O and AB. Each person will belong to one of the four blood groups above. In addition, there are subgroups A1, A2, A3, Ax, B3, Bx, Bm. The Rh blood group system has two main blood groups: RhD positive and RhD negative. Each person will belong to one of the two blood groups above.

Rh negative blood type is a rare blood type that only appears in about 0.1% of the population, not only affecting blood transfusion but mothers with this blood type also have the risk of blood group incompatibility with their children and many risks affecting the health of newborns. To be able to control these risk factors well, do some tests.
