There are four main blood types. Blood type A is the most ancient, and it existed before the human species evolved from its hominid ancestors. Type B is thought to have originated some 3.5 million years ago, from a genetic mutation that modified one of the sugars that sit on the surface of red blood cells.
Can a woman’s blood type change?
During her third pregnancy, she was genotyped as a partial D antigen, which was reported as Rh-negative. Conclusion: Revisions in laboratory procedures for Rh typing may present as a change in the Rh blood type of pregnant women-and as a change in their eligibility for Rh immune globulin.

What is the rarest blood type?
AB negativeWhat’s the rarest blood type? AB negative is the rarest of the eight main blood types – just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don’t struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.
Can you have a different blood type than your parents?
No it doesn’t. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent’s blood type.
Why did my blood type change?
Usually, you will have the same blood type all of your life. However, in some cases, the blood types have changed. This has been due to unusual circumstances, such as having a bone marrow transplant or getting certain types of cancers or infections. Not all of the changes in blood type are permanent.
What is the golden blood type?
The golden blood type or Rh null blood group contains no Rh antigens (proteins) on the red blood cell (RBC). This is the rarest blood group in the world, with less than 50 individuals having this blood group. It was first seen in Aboriginal Australians.
Is your blood type on your birth records?
If you don’t already know your blood type, finding record of it can be difficult – blood type isn’t on your birth certificate and is not typically listed in records from routine lab work. So, you may need to do a blood type test – and that’s actually quite simple.
What happens if one parent is O positive and the other O negative?
Children who inherit an A-O combination will be type A, but, remember, they could still pass that O gene off to their children. As a result, their child could wind up as type O if the other parent passes them an O-type gene, too. That last fact explains how O-positive parents can have O-negative kids.
