Fetal Genetics samples are commonly obtained either by chorionic villous sampling (CVS) between 10-14 weeks of gestation or by amniocentesis after 16 weeks of gestation. Percutaneous umbilical blood sampling (PUBS) is less commonly used and involves taking a sample of fetal blood directly from the umbilical cord.
Fetal DNA identification is a technique that can extract cells from the amniotic fluid of pregnant women and confirm the father-son relationship by identifying the DNA of the fetus (deoxyribonucleic acid). In pregnancy do a prenatal paternity test after the earliest time possible at 8 weeks gestation or 16 weeks of pregnancy but also the time identified by the removal of fluid.
