Which blood group is the rarest?
The rarest blood group in the world is AB-negative (AB-). Only 0.6% of the world’s population has this blood group, meaning it is extremely difficult to find donor blood for people with AB-. Because blood groups are genetic and vary by region, AB-negative is even less common in some populations.
Why is AB-negative so rare?
AB negative is rare because it is a combination of two less common blood characteristics: the AB blood group and the rhesus negative factor.
- AB blood type: Only a small percentage of the world’s population has blood type AB. This blood type occurs when a person inherits an A gene from one parent and a B gene from the other parent.
- Rh negative: Most people are rhesus positive (Rh+), meaning the Rh protein is present on their red blood cells. Rh negative is much less common, contributing to the rarity of AB-.
Because both factors are relatively rare, this makes the combination AB-negative the least common blood group in the world.

How common is AB negative in different regions?
The frequency of AB negative varies by region and population group:
- Worldwide: about 0.6% of the population
- Europe: around 1%
- North America: about 0.5% – 1%
- Africa: less than 0.1%
- Asia: 0.2 – 0.5% on average
Because blood groups are passed on genetically, some populations are naturally less likely to be AB-negative.
What does it mean to have AB negative?
People with AB-negative blood can receive blood from all other negative blood groups (O-, A-, B- and AB-), but can themselves only donate to other AB-negative individuals. This makes it crucial to have enough AB-negative blood donors, as it is difficult to find suitable donors.
Why is AB-negative important for blood donation?
Because AB-negative is so rare, there are often shortages in blood banks. People with AB-negative blood can only receive blood from other rhesus-negative donors, meaning donation of AB-negative blood can be life-saving for patients with this type.
Conclusion
AB negative is the rarest blood group in the world, with only 0.6% of the population having this blood type. The combination of AB blood group and rhesus negative factor makes it one of the most difficult blood types to obtain for transfusions. People with AB-negative are therefore strongly encouraged to become blood donors, as their blood is scarce and valuable for other AB-negative patients. Take a blood type test to find out your blood type.
