What blood group are you pertaining to? ABO blood group? There are other blood groups like Kell, Duffy, JK among those but I guess you are pertaining to ABO which is the common of all. It doesn't change. Once your a type O, you will always be a type O. Rh factor doesn't change too. If you're saying that your Rh factor changed, there could be an error to ur testing. I've worked in a laboratory as a certified Medical Technologist and believe me, errors like that happen... after all, we're just human... So, my suggestion is that you go for another test and for once settle the issue. Knowing your biological parents' Rh factors and blood type will surely help resolve this matter.

No, the Rh factor can not change during life. The only change you can experience is that some parts can get lost or damaged. It is also possible after Blood transfusion to have suddenly Rh pos blood for a while even someone was Rh neg before. Only done in emergency situations.
In Blood banking there is also something called Du, which is a very weak form of the antigen D. These are people they are considered Rh D pos for donating blood (since there is a possibility that they can trigger an Anti body D in the recipients). But the Du person, to be on the save side (not developing an Anti-D) are considered to receive only Rh neg. blood.
The thing is once you have an Antibody against Rh D and receive Rh D pos blood you have a mild to sever hemolytic reaction (can be fatal).
Only in life threatening events or real blood shortage this is even considered.
You can tell I love my job, sorry.
On yahoo answers I try to keep it as simple as possible.
Hope this helps a little.
if you have more questions, e-mail me.

I have actually heard of this happening. It happened to my mother...she used to have B+ and became B -. We do not know why it is still a mystery. You are actually the first person I have ever heard of yet to have this happen besides my mother. All current medical research shows this cant happen ..but obviously it does. Maybe its time for some more research into these occurances. The only this I can tell you is you arent the only one. By the way my mom suffers from a chronic form of a mainly untreatable form of anemia.....and became Rh- during her pregnancy with twins(me being 1). She has a long history of being Rh+ before this. Her mother had tuberculosis while pregnant with her maybe somehow this could be a clue...My mother was in the Army and used to donate blood all the time. Hopefully one day I can find out what caused her Rh to change.

confident, if it is a similar blood variety (A, B, O) or O. The Rh element is the presence of proteins on the cellular and if a terrific Rh (with proteins) is going right into a physique that has blood with detrimental Rh (no proteins), the physique will reject them. not the case any different way around, this is why X- or O- can donate to X- or X+. X being a variable, of direction (edge be conscious: O is seen "conventional" by way of fact A or B blood varieties won't reject it by way of fact they don't have "O" antibodies and O would not have A or B properties).
