Human blood theoretically contains sufficient variables to enable the invididualization of one person from any other. The basis for blood individuality is mainly the multitude of polymorphic enzymes and proteins, most of which are products of genetic variation . These genetic factors are constant throughout life. Both transient and comparatively permanent environmental factors, such as acquired immune antibodies, also contribute to the differentiation of blood between individuals. Any single factor which is decisively different in two specimens at a given time will discriminate between the two and thus eliminate a common source.
