Different Methods of Paternity Testing

Paternity testing is becoming increasingly popular as more and more people are beginning to realize the many answers that paternity tests can provide and the emotional and financial heartache that they can save a person. Paternity tests can determine up to 99% accuracy whether or not an individual is the father of a child. This can be very helpful in child custody cases when a man is claiming that he is or is not the biological father of a child. Depending on the results of the paternity test, the courts can then either force the man to pay child support payments or they can make it possible for a person to discontinue, or not begin to, pay child support payments. There are a few different methods that can be used to determine paternity and these different tests can be done either postnatal, which is after a baby is born, or prenatal, which is before the child is born.

A postnatal paternity test can be done by collecting a DNA sample from both the man in question and the child. This can be done through the collection and testing of blood, a swab from the inside of the cheek, umbilical cord and testing, or through various other kinds of testing such as hair and semen. This is generally considered to be the safest kind of paternity testing as the fetus will not be disturbed while it is still developing in the uterus. However, this is not always possible, or not always the preferred type of paternity testing and so, prenatal paternity tests, which are also considered very safe, must be completed to determine paternity.

Amniocentesis is one form of paternity testing that can be done before the child is born. During this type of paternity test, a doctor will insert a large, thin needle into the mother’s belly and right into the uterus. The needle is used to withdraw a small amount of amniotic fluid and that fluid will be tested. This is possible because the amniotic fluid contains DNA and can then be matched, or not matched, to the man’s DNA to establish paternity. This test can only be done under the approval of a doctor as there are some risks to the developing fetus. Some of these risks include miscarriage; leaking of amniotic fluid, which can also be fatal to the fetus, bleeding and cramping for the mother; and a very small chance of injuring the fetus. Because the doctor will use an ultrasound to guide the needle, these risks are very small but are present and so should not be done on a woman who is considered to be in a high-risk pregnancy.

Another type of paternity test is a Chorionic Villus Sampling, otherwise known as CVS. This type of paternity test will allow a small tube or needle to be inserted into the woman through the vagina, where it can then collect chorionic villi from the inside of the uterus. These villi are present on the walls of the uterus and contain the same DNA as the unborn child. These villi are then tested to establish paternity.

The method of paternity test that is chosen should always be taken into careful consideration as usually, this is an issue that can wait until after the child is born and doing so will certainly carry no risks to the child or the mother but still provide answers to questions regarding paternity.

About the Author

Amniotic Fluid by Evelyn, Columba Sara [Paperback] $66.91 Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Amniotic fluid or liquor amnii is the nourishing and protecting liquid contained by the amniotic sac of a pregnant woman.The amniotic sac grows and begins to fill, mainly with water, approximately two weeks after fertilization. 10 weeks later the liquid contains proteins, carbohydrates, lipids and phospholipids, urea and electrolytes, all of which aid in the growth of the fetus. Amniotic fluid is produced by exudation of fluid through the skin of the fetus up until the 14th week of pregnancy at which point keratinization of skin occurs. During weeks 811, the fetus begins to swallow and urinate, which is why the amniotic fluid contains fetal urine in the later stages of gestation.

Amniotic Sac $60.54 High Quality Content by WIKIPEDIA articles The amniotic sac is the sac in which the fetus develops in amniotes. It is a tough but thin transparent pair of membranes, which hold a developing embryo until shortly before birth. The inner membrane, the amnion, contains the amniotic fluid and the fetus. The outer membrane, the Chorion, contains the amnion and is part of the placenta. Its wall is the amnion, the inner of the two fetal membranes. It encloses the amniotic cavity and the embryo. The amniotic cavity contains the amniotic fluid. On the outer side, the amniotic sac is connected to the yolk sac, to the allantois and, through the umbilical cord, to the placenta. Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 72 Publication Date: 2010/12/16 Language: English Dimensions: 6.00 x 9.02 x 0.17 inches

Prenatal Testosterone in Mind: Amniotic Fluid Studies $20.56 This pioneering study looks at the effects of prenatal testosterone on postnatal development and behavior. Hormonal effects on behavior have long been studied in animals; the unique contribution of this book is to suggest a connection between human fetal hormones and later behavior. It details for the first time testosterone’s effect on social and language development, opening a new avenue of research for cognitive neuroscience. The authors look at samples of amniotic fluid taken during amniocentesis at 16 weeks’ gestation, and relate the fetal level of testosterone (which is present in fetuses of both sexes, although in different quantities) to behavior at ages 1, 2, and 4 years. They argue that the amniotic fluid provides a window into the child’s past–a chemical record of that child’s time in the womb–that allows informed prediction about the child’s future brain, mind, and behavior. This is not the retrospective speculation of psychoanalysis, they point out, but an opportunity to study development prospectively and trace developmental precursors and causes of later cognition. The study suggests that prenatal levels of testosterone affect a range of later behaviors in children, from the inclination to make eye contact with others to the size of the vocabulary. It also suggests that prenatal testosterone level may be related to the development of typically "masculine" and "feminine" behaviors. The study’s ongoing research explores whether fetal testosterone has any link with the risk of developing autism. Connecting endocrinology and psychology, the authors propose that there is a biological component to behaviors often thought to be produced by the social environment.
