Can a person s blood type change?

There is a possibility. However, if your student has never been in good health and has not received any special **, it may be that there was an error in the previous blood test. A person's blood type is innate, and it doesn't change for life.

However, under certain circumstances, a person's blood type can change. Variants after transplantation of bone marrow stem cells. If the recipient's hematopoietic function is completely or mostly replaced by the bone marrow stem cells of the transplanted donor, then the change in blood type is long-term or even permanent, and will not return to the original blood type of the recipient unless the recipient's own hematopoietic function is restored.

Temporary changes in blood type. There are a variety of reasons, such as immaturity of infants and young children, illness, especially cancer, blood transfusions, medication, and radioactivity**, which can change a person's blood type in the short term or superficially. These changes are transient and incomplete, and may revert back to the original blood type once the disease is controlled.

Other than the reasons mentioned above, researchers have so far not found any other way to change a person's blood type. <>

Blood type is inherited, like a symbolic "ID card" with us throughout our lives, basically will not change, but under the influence of some special circumstances, blood type will change. For example, if the bone marrow stem cells are transplanted, the hematopoietic function of the recipient is mostly replaced by the bone marrow stem cells of the transplanted donor, and the blood type will be changed in the long term.

A child's red blood cells are not yet mature, and blood transfusions and radioactivity** can change a person's blood type in a short period of time. The formation of a person's personality will change in addition to the influence of acquired environment, education and other factors, and the congenital factors inherited by blood type will generally not change greatly, so people with different blood types have very different personality traits. <>

Introduction: A person's blood type is a sign of everyone, and there are many blood types, such as blood type A and blood type O.

and blood type B, so what determines one's learning?

In fact, blood type is genetically determined, it is not created in a vacuum, and it is determined by both parents. And this heredity is still relatively distinctive, for example, there are some parents who have the same blood type O blood, then the children they give birth to may also be O blood type, which is why when a person has a large blood loss, they usually look for themselves.

The reason for the blood transfusion is because the probability of the same blood type between the family members is relatively large. And under normal circumstances, a person's blood type has been determined not to change otherwise when they are born, but in fact, if they suffer from any major diseases in the later stage, such as malignant tumors.

In the case of an infection, the blood type will also change, and when a bone marrow transplant occurs, your blood type will also change because of the bone marrow.

In fact, the discovery of blood types and the discovery that everyone's blood is different, is a very significant scientific breakthroughBreak. It's because that's how you can make surgery.

It has become more advanced because blood transfusion is a method that can be used to save countless lives. However, when administering a blood transfusion, the doctor must ensure that the blood type of the two people is the same, and if they are not compatible, then the recipient will die. Normally, the three most common blood types are blood type A, blood type B, blood type O, and human apes that are closely related to humans.

There are also three blood types.

In fact, it is very convenient for many people to test their blood type, usually take a drop of blood on the finger and put it on a diaphragm, and then you can know your blood type by testing it on the instrument. In fact, the blood type is mainly determined by hemoglobin.

The antibodies on the antibody are related to the antigen, the main reason for type A blood is because it contains type A antigen, and type B blood contains other type B antigen, type AB blood.

It means that both antigens are present. In the case of type O blood, there is no antigen and antibody, which is why blood type can be transported to blood type A and blood B.

The blood type is determined by the combination of three genetic factors, A, B, and O, and a person's blood type can be determined according to the blood type of the parents. Because it is a reserve rule for genetic control of blood type.

Biology teachers have said that a person's blood type is inherited from the chromosomes of both parents, so it is determined by the blood type of your parents.

It is determined by the parents' genes, it may also be determined by the factors of the inheritance, it may also be determined by the cells of the parents, and it is also determined by the cells of their own cells.

Genetics. It is generally determined by this, and one's own blood and blood type are determined by one's own parents.

A person's blood type will be determined by the genes inherited, and the child's blood type will most likely be inherited from his or her parents.

In general, blood groups are mostly formed at birth, while the spine is delayed and remains unchanged for life. In some special cases, blood type can be changed.

Blood group transition:

1. The red blood cells in infancy and early childhood are not yet mature, and the blood group antigen is not fully developed, which can make the blood group test different.

2. Some elderly people and patients with malignant tumors can make differences in blood group testing due to the weakening of the antigenicity of red blood cells.

3. Some people are overdosed due to radiation exposure or other reasons, which can lead to genetic changes in the red blood cell system and blood group changes.

4. Some patients with intestinal obstruction or digestive tract tumors can have blood group crossover during the course of the disease.

5. The infusion of a large amount of colloidal solutions such as dextran can adsorb antigens on the surface of red blood cells, which can change the original antigenicity, thereby causing changes in blood type.

The above changes in blood type will change back to the original blood type when the condition improves or the cause of the antigenic change disappears.
