Can in all cases an AB blood group patient can receive blood 4m al other blood groups?

Question

my father had some renial problem & his kidney was to be replaced his blood group is AB , doctors said that only people having blood group O or AB can give blood to him.Why it is so?

Answer 1

because of certain antigens that your blood has. But in the case of AB, they should be able to receive any type of blood as they possess both A and B antigens. Dr's perfer staying with in the same blood type to minimize reactions. O blood can be received by anyone since the other blood types usually don't attack it. Hope this helps!

Answer 2

There are two antigens which identify the ABO blood groups, A and B. A persons red cells can be marked with either one or the other, types A and B, neither, type O or both, type AB. What ever blood type a person is determines what antibodies for ABO groups he has, that is a type A person has anti-B, a type B person has anti-A, a type o person has both and a type AB has neither.
When blood is given to a patient, virtually all of the plasma is removed form the donor blood along with the white blood cells and platelets. Some saline is added to keep the red cells suspended. This also removes all the antibodies. Now your father, as a type AB can recieve any type of red blood cells because he does not have antibodies against any type and since the antibodies from donor cells are removed, there is no problem there. It is still best to give a patient his own type, but in this case there is no danger in giving him another type if type AB is not available

Answer 3

Human blood groups is divided into 4 groups and 2 Rhesus groups.
Group A, B, O and AB, and each of these groups can be Rh negative or positive.
Now, our blood cells have antigens on their surface, to recognise itself.
Group O blood cells have NO antigens at all on their surface and you have antibodies against A and B antigens so against blood that is Group A or B or AB (meaning that if you receive A or B or AB blood, your body will attack those cells and you will die) (Group O Rh- is the universal donor, any blood type will accept this blood type with no adverse reaction)
Group A has A antigens, and B antibodies.
Group B has B antigens and B antibodies.
Group AB has A AND B antigens, so it does NOT have any antibodies and thus can receive any type of blood (usually AB is universal receiver).
Then, for Rhesus type blood, if you are Rh+, then you can receive Rh- blood as this blood has no antigens on its outer surface (same principle as groups). On the other hand, if you are Rh-, you CANNOT receive blood from someone who is Rh+...since your blood has ANTI-Rh+ antibodies.

If your father is AB blood, then he can receive blood from either A, B, O or AB. Except if he is Rh- then he will need Rh- blood as well. Obviously, it is always better to receive blood from your own blood type.
You mean he needs a new kidney? Quite a few ppl can live with only one kidney.

Answer 4

I'm not a physician; but, I learned in Biology 101 that the Universal Blood Donor is one who has Type O Positive blood. All other blood types may only be donors to those of the same blood type.

My blood type is O Negative. I can only safely receive blood from another donor of the same type, or someone with Type O Positive. My blood type cannot safely be accepted by anyone other than another Type O Negative.

Does this mean that my blood type will not be accepted by organizations such as the Red Cross? No. It simply means that every precaution must be made to assure that my blood type is used only for other Type O Negative recipients.

Perhaps your father's doctors may be able to give you a more scientific answer.

Answer 5

O is the universal donor. AB is the universal recipient. I would think the only issue would be the Rh factor.
