从滴血认亲谈开去我国古代就有滴血认亲的说法。在世界上第一部法医著作,宋朝宋慈著的《洗冤集录》中也有滴血认亲的记录,当然,这样的认亲不但不会洗冤,反而更会造成冤假错案。小孩不一定与父母同一个血型,因而血滴在一起会发生凝集,如因此而判为无亲缘关系,岂不“冤枉哉”? Departure from the drop of blood to talk about open to our ancient blood there is a statement of blood deaf. In the world’s first book of forensic medicine, there was also a record of identifying bloodshed with blood in the Book of Songs of the Song Dynasty. Of course, such an identification not only did not injustice, but would even result in unjustly wrongful cases. Children do not necessarily have the same blood type with their parents, so the blood droplets will aggregate together, as a result of which is not unrelated, would not “innocent”.
