—
In the medical world, there is one
blood type
whose existence is so rare that researchers continue to pay attention to it.He is
golden blood
or golden blood type.
Nickname
golden
blood
not about color, but because it is a rare type.It is estimated that only around 50 people worldwide have this ultra-rare blood type.
The rarity of this type has made golden blood a global research topic.Scientists want to understand how this rare condition occurs, the risks it poses to its owners, and whether it is possible that similar blood could one day be produced in a laboratory to help those who need special transfusions.

What is ‘golden blood’?
Reporting from the Cleveland Clinic page,
golden
blood
is the Rh-null blood type, which is a condition when a person has no Rhesus (Rh) antigen at all on the surface of their red blood cells.
Typically, the Rh system has more than 50 types of antigens including RhD.But in Rh-null, everything is gone.
It’s just a term
golden
blood
often confusing because it sounds like this blood is better or safer for transfusion.
The name ‘golden blood’ is just to show how rare Rh-null is, it does not mean it is a better or purer blood type.
Golden blood is classified as very rare because this condition arises due to a genetic disorder that makes a person not have all the Rhesus antigens on the surface of their red blood cells.
This combination of genes almost never occurs in the general population, so only a handful of people in the world have it.
Its rarity is further exacerbated by the complex nature of inheritance and the low probability of two people with similar gene patterns meeting and producing Rh-null offspring.
Can owners of ‘golden blood’ donate blood?
Owners of golden blood (Rh-null) can actually be donors for almost anyone in the Rh system.Because their blood does not have Rh antigens at all, and the recipient’s body will not react or reject the blood.
However, the situation was different when they needed blood.Rh-null owners can only receive blood from fellow Rh-nulls, because every other type of blood still contains Rh antigens that they do not have.
This means that even though they can donate blood to many people, almost no one can donate blood to them.
In comparison, blood type O Negative is known as a universal donor, but it is not suitable for owners of golden blood.The reason is, O Negative still has other Rh antigens which can trigger an immune reaction in Rh-null recipients.
