Blood Type A Antibodies

January 23, 2021

Blood typing is accomplished by mixing drops of blood with sera containing antibodies anti sera against the abo and the rh systems. If the blood cells clump agglutinate the antibody has bound to the appropriate antigen on the cells.

The abo system is the most important blood group system in human blood transfusion since any person above the age of 6 months possess clinically significant anti a and or anti b antibodies in their serum.

Blood type a antibodies. In addition to the a and b antigens there is a protein called the rh factor which can be either present or absent creating the 8 most common blood types a a b b o o ab ab. Antibodies are produced by specialized white blood cells called b lymphocytes or b cells. Each antibody produced by the immune system is matched to a specific antigen like a key to a lock which it then binds to either to kill it or tag it.

There are four major blood groups determined by the presence or absence of two antigens a and b on the surface of red blood cells. This is why it is essential to match blood types when a person needs a. Antibodies are specialized y shaped proteins made by the immune system they help the body fight disease by recognizing viruses bacteria and other pathogens disease causing microorganisms by the molecules on their surface called antigens.

Your cells have type b antigens attached so your body makes antibodies against only type a. The mature b cells called plasma cells secrete millions of antibodies into the bloodstream and lymphatic system. When an antigen binds to the b cell surface it stimulates the b cell to divide and mature into a group of identical cells called a clone.

Blood plasma contains antibodies a type of protein that can fight a substance considered foreign to the host body. The body manufactures antibodies to correspond to naturally occurring antigens inherited through dna. Once the type a antigens are kept at bay your blood cells show type b as the dominant type.

If your blood cells clump only when mixed with. Foreign antigens occasionally introduced by way of pregnancy or blood transfusions will also cause the body to make antibodies. You can receive type a blood or type o blood and can donate blood to those with type a or type ab.

Blood group a contains antibody against blood group b in serum and vice versa while blood group o contains no a b antigen but both their antibodies in serum. White blood cells produce antibodies. Anti a antibodies you have type a blood anti b antibodies you have type b blood both anti a and anti b antibodies you have type ab blood.

These antibodies will target an antigen if they consider it a foreign object. If you are blood type b the situation is reversed. Antigens are markers on the surface of a blood.

If your blood is a positive a it means that your blood contains type a antigens with the presence of a protein called the rhesus rh factor.
