Packed red blood cells type A do not contian enough Anti-B antibody to cause a reaction in AB type people. The plasma (liquid portion of blood) contains the antibodies. This is mostly removed when blood products are processed in a blood bank. Antibodies are what causes red blood cells to agglutinate (clump)

What is the clumping of red blood cells called?

it occur due to mismatch of blood. if recipient is denoted wrong type of blood group for example if a recipient have blood group a if he or she have donated blood group b they the anti antigen A present in blood group b will destroy the blood group A this is called clumping of blood.


Why clumping takes place when ab blood group is given to o group?

due to antigen antibody reaction. it is the principal of the blood group


Name for blood group O person?

A blood group 'O' person is called a Universal Donor from sue b :-)


Can an individual with O blood group donates his blood to an A bloods group person?

An individual with an "O" blood type can be transfused to any other blood type, since type "O" blood is the universal blood type. This includes an "A" blood type.


Type o blood doesn't have what?

Type O blood group's RBC doesn't have any antigen on it's surface, that is why it can be safely transfused to any person(at last theoretically).


What could go wrong if blood type A is put in a patient having blood type B?

The antibodies in blood group B will destroy the blood group A cells. They will actually cause clumping and therefore clots which will cause a heart attack.


What is a hemolytic reaction to a blood transfusion?

Most severe type, but rare incompatible blood incompatibility in multiple transfusions. Mostlikely to occurs when transfused red cells react with circulating antibody in the recipient with resultant intravascular hemolysis. When a group O patient is mistakenly transfused with group A, B, or AB blood. Patients receiving a major ABO- incompatible marrow or stem cell transplant with sufficient red cell content will likely develop an acute hemolytic reaction. Symptoms are: fever, chills and fever, the feeling of heat along the vein in which the blood is being transfused, pain in the lumbar region, constricting pain in the chest, tachycardia, hypotension, and hemoglobinemia with subsequent hemoglobinuria and hyperbilirubinemia. Prevention: proper identification of patients, pre-transfusion blood samples and blood components at the same time of transfusion.


Who donate to group o negative?

People with O negative blood are often referred to as "universal donors" because their blood can be transfused to patients with any blood type. Therefore, anyone can donate O negative blood to individuals in need, regardless of their own blood type.


How the blood group is checked?

Blood group is typically checked using a blood typing test, which involves mixing a small sample of blood with specific antibodies that react with the A and B antigens present on red blood cells. If agglutination (clumping) occurs, it indicates the presence of that specific antigen, helping to determine whether the blood type is A, B, AB, or O. Additionally, the Rh factor is assessed to determine if the blood is positive or negative. This process can be performed in a laboratory or with portable blood typing kits.


is A positive blood a universal donor type?

O negative is the universal donor because when O+ve blood group is transfused to -ve blood group recipient, antibodies are produced which causes hemolysis of Rh +ve labelled blood cells. When O-ve blood is transfused to Rh +ve recipient, no antibodies are produced as donor blood has no Rh factor present on blood cells, so no transfusion reaction occurs. Thus, O -ve is universal donor.


What happens if anti-B antibodies are mixed with group B red cells?

If anti-B antibodies (from someone who is blood type A or AB) are mixed with group B red cells, agglutination or clumping of red cells will occur due to a reaction between the antibodies and the B antigen on the red cells. This can lead to transfusion reactions if incompatible blood is transfused, causing harm to the recipient.


Why blood type ab cant donate to the other blood type?

Type A, Rh negative red cells can be, and are frequently, transfused to AB, rh negative recipients. Type A, Rh negative whole blood, however, cannot be given to an AB, Rh negative recipient as anti-B antibodies present in the unit could cause an acute, hemolytic transfusion reaction. Whole blood transfusions are rarely used in modern transfusion medicine.
