Agglutination in hematology

Hemagglutination
The 'bedside card' method of blood typing, in this case using a Serafol card. The result is blood group A positive.
Hemagglutination is when the particles involved are red blood cells. The agglutin is called hemagglutinin.
In
cross-matching, agglutination occurring when donor and recipient's blood are incubated together indicates that the donor blood is incompatible for that particular recipient.

Leukoagglutination
Leukoagglutination is when the particles involved are white blood cells.
An example is the PH-L form of
phytohaemagglutinin
