ABSTRACT
Serologists estimate that 80% of the human population secretes water-soluble antigens called agglutinins in their body fluids (saliva, semen, tears, and perspiration) that can be used to determine the ABH blood group classification of a person [4-7]. Also, finding salivary amylase on an injury site might confirm the injury is a bitemark when this is not readily apparent from the physical appearance of the wound [8-11].
