secretor

(Science: haematology, physiology) An individual whose bodily fluids (saliva, semen, vaginal secretions) contain a water-soluble form of the antigens of the aBO blood group.

Secretors constitute 80% of the population. In forensic medicine, the examination of fluids has enhanced the ability of law enforcement officials to develop identifying information about perpetrators and narrow a field of suspects.
