Yes, the red blood cells are the most common type of blood cells, they are followed by white blood cells frequency. There are also, platelets, which aren't technically considered cells, but are more frequent than white blood cells and less frequent than red blood cells.
The EOS percent is the percent of white blood cells in the blood. The eosinophil count is used when testing for Allergies.
The size of blood cells is not a factor in determining a person's blood type. Blood type is determined by a combination of certain proteins in the cells.
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.
Red and white blood cells.
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.
Red blood cells
Type O blood because type O blood has no markers on the blood cells so the anti-markers will not go into action against the blood cells.
red and white blood cells
Yes, blood cells from a person with type B blood will agglutinate when mixed with type A antiserum. This is because the type A antiserum contains antibodies that recognize the A antigen present on type A blood cells and can cause them to clump together.
They are ordinary blood cells.
