Type B blood is rarer than type A and O, but more common than type AB. Individuals with type B blood have antigens in their blood that will attack other blood types if introduced to the body, leading to a hemolytic reaction.
Approximately 9.4% of the population has the B+ blood type.
B negative varies depending on countries, but in the U.S. about 1.6 percent have that blood type.
According to the red cross website AB- is the rarest blood type, but B- and AB+ are also rare. Ethnicity may impact blood type: O- is rare in Asian people but relatively common for Caucasians.
Only 2% of the world's population has type B negative blood. The only blood type that is rarer is AB negative. It is a very rare blood type and very needed to help others.
AB blood type is rare. It is also a rather new blood type. People with this blood type have qualities of people with A and sometimes characteristics of those who have type B. Less than 5% of the population in America has this.
AB - blood type is the rarest blood type, followed by AB + being the second rarest. Its usually not good to have a rare blood type, considering that its rare and if you ever need a blood transfer, your blood type would be harder to find. If your considering donating your rare blood, it'll definitely be useful towards the other few people with the same blood type that need a transfer.
Rare blood types are O negative and AB negative. B negative and AB positive are also fairly rare blood types. O negative is known as the universal donor blood type because it is compatible with any other blood type.
B positive blood is a rare blood type, negatives include higher than normal cortisol levels in situations to stress and a vulnerability to autoimmune diseases.
I would say the most uncommon blood types are the negative types. Which include O-, A-, B- and AB-. AB+ is quiet rare too but not as much as the negatives. AB- is currently the most uncommon blood type.
AB negative is the rarest blood type. AB positive is the second rarest blood type. The negative blood types are more rare than the positive. The common blood type is o.
There are many bloodtypes--both positive and negative. I know, from experience, that o positive blood type is not rare. It is used as the universal donor. A-, B-, AB- are known to be rare blood types. I believe o- is a rare blood type, as well. A good book from the public libary would further esplore the many different blood types and the statistics correllated with specific blood types.
Some rare types of blood include the Bombay blood group, which lacks some common antigens, and the Rh-null blood type, which lacks all Rh antigens. These rare blood types can make finding compatible blood for transfusions more challenging.
