I have ab negative blood type?

Question

My blood type is AB negative. I was recently told it is very rare. Does anyone now how rare it really is and why it is so rare?

Answer 1

0.6% in the USA

I don't know the exact reason that it is uncommon except that it is hereditary.

Answer 2

Hi there Amanda

Thank you for allowing me to answer your interesting question. A blood

type (sometimes called ABO blood group is determined by the presence or absence of two proteins (Protein A and Protein B) on the surface of a persons red blood cells. Because two proteins are involved, there are four possible combinations or blood types (ABO groups):

Type A - Only the A protein is present.

Type B - Only the B protein is present.

Type AB - Both proteins are present.

Type O - Neither protein is present (almost 40% of the population).

A third protein called the Rh Factor (named for its discovery in the

blood of a Rhesus Monkey) determines whether the type is positive or

negative. If the Rh protein is in the blood it is considered positive and if the protein is absent the type is classified as negative. So now you can guess

Only about 1% of the population has an AB Negative blood type. The

type is indeed quite rare but this does not necessarily preclude an AB

Negative person from receiving an urgent transfusion from certain

donors.

In an emergency, anyone can receive type O Red Blood Cells, and type AB individuals can receive Red Blood Cells of any ABO type. Therefore, people with type O blood are known as universal donors and those with type AB blood are known as universal recipients.

Generally speaking though, persons with AB Negative Type Blood can

RECEIVE the following types of blood:

A Negative

B Negative

O Negative

AB Negative

AB Negative type blood can be safely GIVEN to persons with blood types:

AB Positive

AB Negative

If you are involved in an accident or found yourself in need of blood,

the likelihood that you would receive AB Negative blood depends

largely on what facility you are treated at and what inventory they

have on hand. As a rule, you probably would not received AB Negative

blood as a replacement since it is so rare and limited supplies of it

exists in most facilities. On the other hand, being a universal

recipient and in view of the fact that Type O, a universal

replacement is so widely available, this is most commonly what would

be used and you would probably not be critically in need of

replacement blood for very long. In other words, the fact that you

have this particularly rare blood type would not mean a life or

death situation for you under normal circumstances.

In Summary:

1) AB negative is a blood group that has both protien A, B and Rh is absent.

2) Only 1% of the world has it. Reason- see 1) rare to have all these 3 things

3) Most importantly---Its OK!! to be so rare :))) U can still get blood from other donors- in case of emergency u will be OK.

Hope this questions meets or exceeds your expectations

Cheers !

Answer 3

Less that 1% of the population Have that particular Blood group.

This is due to the fact that type AB blood is the least common type of blood in virtually all populations and, furthermore, Rh negative blood is typically found in only 15% or less of any population.

The exact percentage of AB negative blood varies among different ethnic groups and in different geographic regions. For example, the overall U.S. average is approximately 0.6%, the value in African-Americans is about 0.2%, and the value in Oriental-Americans, Hawaiians, North American Indians, and Australian Aborigines is virtually zero percent.
