ABSTRACT
Blood typing has been used for many years in forensic science and was the main source of blood determinations prior to deoxyribonucleic acid (DNA) being introduced as a more conclusive form of evidence. Four main blood types are used for identification purposes, but there are eight groups, which are more specific and relate directly to the antigen present in the blood. In addition, the basic A-antigen and B-antigen in an individual’s blood will also contain the presence of an Rh factor of positive or negative.
