Yes, it is possible. In a bone marrow transplant, all of the patient's bone marrow is destroyed and replaced with donor marrow. Since red blood cells are created by bone marrow, the donor's blood type will determine which type of red cells are produced, as explained here: Does my blood type change after SCT or BMT? Yes. The recipients blood type ...

This is something to be confirmed by your doctor and I'm not sure why you're worried, but ABO blood group incompatibilities between the mother and child does not usually cause hemolytic disease of the newborn (HDN) because antibodies to the ABO blood groups are usually of the IgM type, which do not cross the placenta. However, in an O-type mother, IgG ABO ...

Kinda interesting question IMHO, let me break it down a little. First, let's tackle the ABO system. Here you are transfusing O into O, so that would be perfectly fine. Secondly, the is the Rhesus factor. Rh+ erythrocytes have a special antigen on their surface, and if the recipient has antibodies against that antigen, that would cause problems (for ...

If a child has blood type O, it means both his alleles are recessive (since A and B are dominant over O); one of them he gets from their mother, and the other one from their father. That means that the father must have at least one recessive allele that he transfers to the offspring; so the possibilities of the father's genotype are OO, AO or BO. As for the ...

Donate blood. Blood donation is free. If you are a healthy individual who is eligible to donate blood, for example to the American Red Cross, they will need to test your blood for basic type (ABO and Rh), various antibodies, etc. You will not get this information immediately when you donate, but you can access it later on request, or you may be mailed a ...

The article The importance of weak ABO subgroups has a section on this, in addition to general information on what weak subgroups are. All quotes in this answer areas from that study. Weak blood types Weak blood types can be caused by a person having a mutation that leads to not expressing the type A or B antibodies as much, or by mutations in the genes ...

I'm writing a story, in which the detective will recognize a prescription for the victim is for relief of some genetic condition. You wanted to be realistic: In the autopsy report (after any murder, they usually cut the corpse open and search for clues - and for causes of death), the genetic condition would have usually shown. Usually, diseases/...

You are right that any foreign biological material would normally be attacked by the immune system. That is why people have treatments such as chemotherapy and radiotherapy to erradicate their own bone marrow stem cells and thus suppress their immune function before the transplant. This reduces the risk of the transplant being rejected. From Medline: ...

Very rarely, The AB father plus O mother scenario you describe can cause a disease: https://en.wikipedia.org/wiki/Hemolytic_disease_of_the_newborn_(ABO) More commonly, Rh-positive father plus Rh-negative mother can cause a disease: https://en.wikipedia.org/wiki/Rh_disease I can't find any reports of the mother suffering any ill effects from the baby's ...

There are no stupid ideas, this is a very good question. Unfortunately the answer is you can't do this - what determines the blood type is the presence of antigens on the surface of red blood cells. Simply put, antigens can trigger certain responses from the immune system. Here are the four types: Type A: Only the A antigen on red cells (B antibody in the ...
