How old does the child need to be for a paternity test ?
6. There is no age limit with DNA paternity testing. A child which is a couple of days old can be tested with a painless method using a buccal swab sample ( similar to a q – tip). No blood testing is required. DNA paternity testing can be performed on an unborn child between the 10th and 12th week of pregnancy. Newborn children can be tested by collecting blood from the umbilical cord on the day of birth. If the child is a minor, it is absolutely required that the legal guardian provide consent for the child to provide a sample and be tested. If the child is 18 years of age or older parental consent is not required.
