If someones blood cells have type A antigens what type of blood do they have?

People with type A blood can give blood to people with type A or type AB, but you do need to take the Rh factor into consideration. The Rh factor is what makes a person have type A+ or type A-, etc. There are also other types of very rare antigen in the blood that make up the other blood type which is beyong the scoop of discussion here.

What are the A B AB and O blood groups distinguished by?
Blood types are distinguished by the type of antigen on the red blood cells. Type A has A antigens, type B has B antigens type AB has both antigens and type O has none.
A persons blood type depends on the presence or absence of certain proteins called?
A & B antigens on the surface of the read blood cells
Why can't you give type B blood to type A?
The short answer is that the Type B patient has antigens for that specific blood type, so when type A is mixed with the type B, the antibodies in the B blood kill the A blood cells, making it useless.
What are the 4 blood types?
There are four types of human blood, grouped into different catogories. Type 'A', 'B', 'AB' and type O. Each letter refers to a kind of protein or antigen, on the surface of the red blood cells. The surface of red blood cells in Type 'A' blood, has antigens known as A-antigens. Type 'B' blood is determined by it's lack of antigens, which are carried to the surface of red blood cells. Type AB blood is considered the universal recipient because people with this type can receive any blood type. Type O blood is considered the "universal donor" because it can be donated to people of any blood type. Antigens: An antigen is a substance that prompts the generation of antibodies and can cause an immune response
How is blood type o a universal doner?
There are 4 blood types (A, AB, B, and O) excluding the pos or neg aspect, which are all based on the Antigens on the surface of the Red Blood Cells (RBCs). These antigens are what Antiboies detect and bind to and, because antibodies each bind two antigens, they join up all the cells making massive structures that cannot flow through the blood and cause clots. So for example the A antigen will be detected by the anti-A antibody and cause the clott to be forlmed. For this reason we do not have in our systems the antibodies capable of dececting our own antigens, so if you have A antigens (type A blood) you will have only anti-B antibodies and vice versa. If you have both A and B antigens (AB blood) you will have neither anti-A nor ant-B antibodies. If you have no antigens (type O blood) you will have both the anti-A and anti-B antibodies. Recieving donor blood which as antigens to which your own antibodies will be atracted will mean that the blood you receive is clotted up. For exampl is a type A (has anti-B antibodies) receives type B blood (has B antigens) then the antibodies will bind the donor cells. However if a type AB (no antibodies) receives any sort of donor blood it will accept it freely as there are no antibodies tobind any antigens. This is why AB type is known as the Universal Reciever, as it can receive blood from any blood type donor. So if a type O (with both antibodies) receives A type or B type or AB type donor blood then it has antibodies that will bind any of them causing a clot. However O type blood also has no antigens on it RBCs so no matter what antibodies are present the cells will not be bound. This means tha O type donor blood can be put into any resipient without feer the recipients antibodies will bind the cells, and thus O type blood is known as the Universal Donor.
What are antigens determining blood type carried on?
Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.
What cells marks antigens?
the t type white blood cells
Does Type B blood have A antigens?
No, type B blood does not have A antigens. Type B blood has B antigens.
What are the A B AB and O blood groups distinguished by?
Blood types are distinguished by the type of antigen on the red blood cells. Type A has A antigens, type B has B antigens type AB has both antigens and type O has none.
Why is it safe to transfuse blood group O to a patient?
Red blood cells of different groups have different molecules on the surface of their cells these are called antigens. People with blood type A will reject B type blood as they have different antigens on the surface of their cells, these differences are detected by antibodies. Blood type O has none of these antigens and so isn't rejected/detected by the antibodies.
What does having type A blood mean?
Type A has B-antigens on the outside of the blood cells. Type AB has both A or B Anti-gens on the blood cells. Type O has neither on the outside of the blood cells. Antigens detect what type of blood cells surround them. If type A came into contact with type B they would create a clump. For this reason type AB blood can recieve blood from ANY blood type but only give to type AB.
