Rh null, additionally referred to as golden blood, is the world’s rarest blood sort. It may be given to virtually anybody, however only some individuals on this planet have it.
- Rh-null blood lacks all 61 Rh antigens, making it extraordinarily uncommon and medically worthwhile
- It might save lives as a common donor inside uncommon blood varieties
- Rh-null people can solely obtain blood from different Rh-null donors, making transfusions very troublesome
Golden blood or Rh null blood is among the rarest blood varieties on this planet. It’s so uncommon that scientists as soon as thought it won’t even exist in actual life. Whereas most individuals have one in all eight widespread blood varieties (A, B, AB, or O — every both Rh optimistic or Rh destructive), these with Rh null have one thing extraordinary: not one of the 61 Rh antigens discovered within the Rh blood group system (1✔ ✔Trusted Supply

This complete absence makes Rh-null blood extremely distinctive and very worthwhile.

The Discovery
Rh null blood was first found in 1961 in an Aboriginal Australian girl. Scientists had been shocked when her blood pattern confirmed zero Rh antigens. Till then, it was believed that an individual couldn’t survive with out at the least some Rh antigens. However this discovery proved in any other case. Since then, fewer than 50 individuals worldwide have been recognized with Rh null blood.
“That is gold blood,” mentioned Dr. Thierry Peyrard, Director of the Nationwide Immunohematology Reference Laboratory in Paris, in an interview with Mosaic.

A Common Lifesaver
What makes golden blood so distinctive is that it may be given to virtually anybody with uncommon Rh-related blood issues. In that sense, it acts like a common donor inside this small group, which is why scientists and blood banks deal with it like liquid gold.
Nonetheless, this life-saving potential comes with a uncommon threat. Individuals with Rh null can solely obtain blood from one other Rh null donor. This makes transfusions extraordinarily troublesome, usually requiring worldwide searches and frozen samples saved in specialised facilities.

How It Occurs
Your blood sort depends upon proteins referred to as antigens discovered in your crimson blood cells. The Rh system is among the most complicated, with over 60 totally different antigens. Rh null occurs when all of those antigens are lacking, normally due to genetic mutations, particularly involving the RHAG gene. This gene is crucial for creating the Rh proteins that assist maintain crimson blood cells steady.
With out these proteins, crimson cells grow to be fragile and should break aside simply — a situation often called hemolysis. This could result in power hemolytic anemia, which causes signs like fatigue, pale pores and skin, or jaundice. Some individuals with Rh null could not present any signs in any respect, however the situation can nonetheless pose critical dangers.
Golden Blood in India
India’s first recognized case of Rh null blood was found in Gujarat on July 14, 2022. A 65-year-old man was present process assessments for coronary heart surgical procedure when medical doctors seen his uncommon blood sort. The invention sparked nationwide consideration and was added to the nation’s blood registry to assist in future emergencies.
Actual-Life Challenges
As a result of Rh null blood is so uncommon, it’s not obtainable in common blood banks. As a substitute, it’s saved in worldwide facilities and tracked rigorously. Some Rh null people donate recurrently to make sure that small reserves can be found, particularly in pressing circumstances.
For instance, a current case in Indonesia concerned a toddler with Rh null who urgently wanted a transfusion. It triggered a nationwide search and highlighted simply how essential uncommon blood donations are.
Why It Issues
Rh null blood is perhaps extremely uncommon, but it surely saves lives. It additionally offers scientists worthwhile insights into how crimson blood cells work and what occurs when key proteins are lacking.
Individuals with golden blood must take particular precautions, like sporting medical alert bracelets, informing medical doctors earlier than any surgical procedures, and staying linked to world donor networks. For them, each drop really counts.
