Can a person s blood type change?

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.

1) 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.

2) 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.

Can blood type really determine a person's fate? Is it scientific judgment or speculation?

Upstairs said it had been done.

Bone marrow transplant. changed.

Hematopoietic stem cells.

The blood type will change.

Theoretically, this is possible, but usually when a transplant is done, a donor with the same blood type is found, so the blood type is still the same as before. That is, it will not change.

A person's blood type is determined from the day the fetus is conceived, and it generally does not change from birth to the end of life. However, there are some special cases where a person's blood type may also change.

1.Blood group changes after stem cell transplantation.

2.There is also a type of blood group change that is temporary or incomplete blood group change, so it is not considered a blood type change in essence. There are many reasons for this temporary change in blood type, such as immature infants, diseases, especially cancer, blood transfusions, medication and radioactivity**, etc., Du Xiang Congqin can change a person's blood type in the short term or superficially.

For example, if a patient is infused with a large amount of colloidal solutions such as dextroside in a short period of time, the colloidal molecules in the solution may adsorb the antigens on the surface of red blood cells, which can change the antigens of the original red blood cells of the patient, which will also cause changes in blood type.

However, these changes are short-lived and incomplete, and the blood group may change back to the original blood type once the disease is controlled.

In addition to the above reasons, no other way to change a person's blood type has been seen so far.

Yes, the legal program once told an example of a man who had leukemia and later changed his bone marrow, and his genetic blood type changed after recovery. But after all, it is not impossible to have less.

No, blood is made from bone marrow hematopoietic stem cells.

I don't know why you ask, but I can explain theoretically, the genes don't change if the blood type doesn't change, and the popular point is that it won't, but the world is so big, there are no surprises!!

It should be possible, there is an example told in the legal program.

According to the current medical technology, you can't achieve this ideal!
