One of the most important researchers of blood groups is Ludwik Hirszweld, but it was Karl Landsteiner who first made a breakthrough discovery in 1901. He noticed that on the surface of red blood cells there are two antigens responsible for the cells sticking together. It was based on his research that Hirszweld distinguished 4 basic blood groups: A, B, AB and O.
What are the blood types? One of them is unique and very rare
Each of the 4 basic groups has a negative or positive Rh factor. Blood group A has the A antigen on its blood cells, group B has the B antigen similarly, while group AB has both antigens and group O has none at all. This is the simplest distinction between different types, but the already mentioned Rh factor is also an important feature.

This factor determines the blood type and is inherited. It is nothing more than a substance called an antigen that stays on the surface of blood cells. The Rh factor was discovered in 1939 and called the D antigen. Most often it is negative or positive, but as it turns out, There is an extremely rare blood group that has Rh neutral or otherwise called Rh-zero.
What is the “golden” blood group? Less than 50 people in the world have it
This blood group is called “golden blood”. only 43 people around the world. It was first discovered in 1961 in an indigenous Australian woman. It is inherited from the parents, but there must be a mutation in the RCHE gene. However, having “golden blood” is not a privilege at all, because Rh-zero owners can only receive blood from their group. However, they can donate it to people with the Rh- and Rh+ groups.
