Rhnull or "gold blood"

Rhnull is a rare blood type that does not contain Rh antigens in red blood cells. Also dubbed "gold blood" because of its extreme scarcity, only 1 in every 6 million people are considered to have this phenotype.

When scientists continue to learn more about the Rhnull phenotype, it's important to let your doctor know that you have this type of blood if you need a transfusion. Due to the scarcity of gold blood, there is a small group of regular donors around the world.

People with Rhnull's blood phenotype may also be at risk of developing chronic hemotic anemia, which causes your body to destroy immature red blood cells.

Why is blood type important?

Your immune system naturally contains protective substances called antibodies. This helps fight foreign objects that are not recognized by your immune system. Usually, they attack viruses and bacteria. But antibodies can also attack antigens that are not in your natural blood type.

For example, if you have type B blood mixed with type A blood during a transfusion, your antibodies will destroy blood cells with antigen A. This can be fatal, which is why worldwide medical centers have strict procedures to prevent this from happening.

To add to the complexity, blood types don't always have to be the same exactly to be compatible. For example, AB blood has antigen A and B, so that someone with this blood type can receive type A or B blood.

Everyone can accept blood type O because it does not contain any antigens. This is why people with blood type O are considered universal donors. But people with blood type O can only accept blood type O.

In terms of Rh factors, people with Rh-positive blood can receive Rh-positive or Rh-negative blood, while people with Rh-negative blood can only receive Rh-negative blood.

In some cases, a person with Rh-negative blood can carry a child with Rh-positive blood, resulting in a dangerous condition called a Rh mismatch.
