How was the golden blood discovered

"Golden Blood": This is the rarest blood type

This blood type is so rare that only around 50 people have it in the world. Why they are so important.
In contrast, blue blood quickly becomes moldy. Because the superhero among the blood groups is someone else. And he has typically heroic qualities: he can save others, but cannot be saved himself and his blood type poses a potential danger for him.

In the case of blood transfusions, the recipient's blood group must match that of the donor. Medicine has had this knowledge for over 100 years. Therefore, before the discovery by the hematologist Karl Landsteiner, there was a high number of people who died in blood transfusions.

The doctor was the first to classify the skin blood groups into A, B, AB and 0. The Rh factor must also match. It's usually positive or negative. There are sub-categories for this. So there are eight groups in total. Today we know how simplified this representation is and that there are actually millions of different possible combinations of blood groups.

The antigens, a form of protein, are found on the red blood cells. There are about 350 of them in total that are known about. These are responsible for recognizing and destroying foreign blood cells. A has an A antigen, B has a B antigen, AB has both, and 0 has none.

Comment now The perfect blood donor

People with a golden blood group have a special position here. Because your blood can be applied to any blood group because it does not have any of the possible antigens and the body does not identify the foreign blood cells as foreign. They are therefore of inestimable value for medicine.

Conversely, this is precisely the disadvantage for them. If they needed a blood donation themselves, probably not many people would be eligible. They might not get a transfusion if nobody with the Rh factor 0 is found.

Around the world, around nine people with Rhesus zero blood group are registered as donors, while in Europe only one Rhesus zero donor is currently known. The Swiss person has already saved the lives of several people.

A rhesus negative is also rare among blood types. It occurs in around three percent of the world's population.

The find was first documented by an Australian aborigine in 1961.

Apart from that, the special Rh factor has no health effects. Many suffer from anemia.
