To know which blood group each person belongs to, it is necessary to know what components are in the blood, how many types of blood are there, what blood group is, then conduct tests and read the results to determine the blood group.1. Composition of blood
1.1 Plasma is the liquid part of blood and makes up about 60% of the blood's mass. Plasma is mainly water but contains various proteins and other substances such as hormones, antibodies, enzymes, sugars, fats, salts, etc.1.2 Blood cells Blood cells make up about 40 % by mass of blood and can be seen under a microscope. Hematopoietic "stem" cells in the bone marrow are responsible for the production of blood cells. When you have a blood test or blood group test, there are 3 main types of blood cells, which are:
Red blood cells These are the cells that give blood its red color. There are about five million red blood cells in a drop of blood. To replace old broken cells requires a constant number of new red blood cells, millions of these new red blood cells are released from the bone marrow into the bloodstream every day. Red blood cells contain hemoglobin, which attracts and combines with oxygen, allowing red blood cells to carry oxygen from the lungs to other parts of the body.
White blood cells There are many different types such as neutrophils (polymorphonuclear cells), lymphocytes, eosinophils, monocytes, and basophils. All types of white blood cells are part of the immune system and are primarily involved in fighting infections.
Platelets Platelets are very small and have the function of clotting blood when injured..
2. Blood group test
Conduct a series of tests that can identify antigens on the surface of red blood cells, from which blood type can be determined.Of the many different types of specific antigens present on the surface of red blood cells, the ABO and Rh antigens are the most important because of their strongest immunogenicity.
Routine blood group testing aims to determine blood group according to the ABO and Rh blood group systems. In addition, testing for other antigens on the surface of red blood cells is done in a number of other situations.

2.3 Determination of blood type Each person's blood group depends on the type of antigen present on the surface of red blood cells. This antigen is regulated by genes inherited from the person's parents. There are blood groups are:
Blood group A+: have A antigens and Rh antigens. Blood group A-: has A antigens but no Rh antigens. Blood group B+: has B antigens and Rh antigens. Blood group B-: has B antigens but no Rh antigens. Blood group AB+: has A, B and Rh antigens. Blood group AB-: has A and B antigens but no Rh antigens. Blood group O+: does not have A or B antigens but has Rh antigens. Blood group O-: no A, B or Rh antigens.
3. Where can blood grouping be performed?
Vinmec Hai Phong International General Hospital is the only hospital in Hai Phong that has a very modern Spanish Wadiana fully automatic blood grouping machine. Here, customers can perform ABO/Rh (D) blood grouping on an automated machine. The automatic blood grouping allows to minimize errors compared to manual methods.The blood grouping assessment process is performed by a doctor with professional experience: Doctor Pham Thi Thuy Nhung and a team of well-trained technicians help the testing process to be rigorous and rigorous. discipline, comply with regulations, help ensure absolute accuracy.
