Yes they are, primarily in sites of inflammation. WBCs (white blood cells) will migrate to sites of infection and gather there. An example of this is pus. The neutrophil is the predominant WBC in pus and is responsible for giving it its whitish color. Neutrophils are phagocytes and will cluster at a site of infection so that they can eat, or "phagocytose", the foreign invader. Another example would be antibodies secreted by T cells. One way that antibodies disable antigens is by completely surrounding them. An antigen coated in antibodies can no longer perform its function of infecting a cell or proliferating.
Agglutination
agglutination
An agglutination test is a test in which the use of a blood serum results in the agglutination of bacteria or foreign blood cells. The test is used to check for infection and to find pathogens as well as blood types.
they clump together
agglutination
There are five components of blood. The components are red cells, white cells, platelets, plasma and agglutination.

what happens when blood type AB is mixed with blood type A or B?
agglutination occurs depending on what your blood type group deems as an invader. one blood type group may deem wheat lectins as harmfull and will cause the blood to agglutinate in order to protect / repair.... another will not. simply put " one mans food is another mans poison "
T cells
agglutination
Yes, clinically speaking this is the reason you can not put any blood into anyone. when blood cells agglutinate, many blood vessels are blocked, and the recipient of the blood goes into shock and may die.
