In a breakthrough that could hasten establishing paternity and put an early end to paternity disputes, researchers said they now can identify a baby's father months before birth. The method could have significance in medical and legal work that could affect residents of St. Louis and the rest of the U.S.
The newly developed method uses fetal DNA in the mother's blood to determine paternity as early as the eighth week of pregnancy, according to a report in the New England Journal of Medicine.
