Blood Types?

Question

What is the difference between A-antibody in bloodtype B, and B-antibody in bloodtype A. Bloodtype AB does not have any antibody's in ther plasma. What is the importance of having antibody in the plasma?

What is the difference of antboyd A and B?

I just don't understand, why blood type AB does not have any antibodies, why is that? And what is the difference of antibodies A and B? What function has antibodies A and B?

Answer 1

What you must realise is that Types and antibody are seperate things, also plasma and platelets are not type specific. This link may help. O neg is universal donor.

I am a paramedic and I work at my local blood bank as a donor services tech/ platelet tech.

Answer 2

Your red blood cells have protiens on them called antigens. Your immune system will make antibodies for various foreign protiens including blood cell antigens.
a) If u are blood gpA it means your RBC red blood cells have A type antigen on them and your blood has antibodies to antigen B

b) Iikewise if your are gpB then your RBC's have B antigen and your blood has antibodies to antigen A.

c) If you are AB your RBC's have both A and B antigens but no anti A or anti B antibodies.

d) If u are gb O that means your RBC have no antigen on them and your plasma has both anti A and anti B antibodies.

So if say you were gpA. and you got a blood transfussion from someone who is gpB or AB the anti B antibodies would attack and kill every foreign blood cell with B antigen on it. and a transfussion reaction would occur.

By the same reason Ogp can dontate to anyone.
AB can take blood from anyone.

Antibody - any of numerous Y-shaped protein molecules produced by B cells as a primary immune defense, each molecule and its clones having a unique binding site that can combine with the complementary site of a foreign antigen, as on a virus or bacterium, thereby disabling the antigen and signaling other immune defenses.

Antigen - any substance that can stimulate the production of antibodies and combine specifically with them.

Blood types - Each blood group is represented by a substance on the surface of red blood cells (RBCs). These substances are important because they contain specific sequences of amino acid and carbohydrate which are antigenic. As well as being on the surface of RBCs, some of these antigens are also present on the cells of other tissues. A complete blood type describes the set of 29 substances on the surface of RBCs, and an individual's blood type is one of the many possible combinations of blood group antigens; usually only the ABO blood group system and the presence or absence of the Rhesus D antigen (also known as the Rhesus factor) are determined and used to describe the blood type.


Okay, in layman's terms:

There are 4 blood groups: A, B, AB, and O. Out of these 4 groups, there are sub-categories based your Rhesus factor (Also called Rh factor, and is indicated by - or + after the blood type).

The importance of having antibodies is that it helps the body determine foreign invaders. You have all types of antibodies, for instance if you have recently had a cold or the flu, you will have the antibodies for those viruses in your blood.


Antibodies and antigens determine who you can give blood to, and who you can receive blood from. For instance, a person with O+ blood is called the universal donor, because they can give to anyone (they have both A and B antibodies). A person with AB+ blood is called the universal recipient, because they can receive blood from anyone. However, a person with B type blood cannot receive from a person with A type blood because of the antigens.

Was that enough info?

AntiGENS... Antigens... you're wanting to talk about Antigens...

"Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals."
