Agglutination is the reaction of an antibody naturally present or produced in plasma - agglutinin - with certain antigens on the red cell membrane - agglutinogen - forming a cluster of small cell masses.
This reaction can be used to identify a person's blood type and has consequences when blood transfusions are performed. Because an individual may or may not contain antigens in their red blood cells, the agglutination process will occur when the donor's blood has an antigen that is not present in the recipient's blood. In this case, the immune system will recognize this foreign body and react by agglutinating red blood cells, leading to death.
The most common plant-based subtitute for cow milk are either soy milk or almond milk. In term of fat and protein ration, these plant based milk are pretty much similar. The advantage that the plant based milk has is that it tend to contain more fiber, but on the downside, cow milk tend to contain more calcium.
