In this day and age DNA testing seems as routine as filing a birth certificate. However, that is simply not true. In many cases DNA testing can be invasive and dangerous. This is particularly true in some cases of prenatal DNA testing. Before you agree, or ask someone to agree to prenatal DNA testing you need to know the ins and outs of the procedure and what options for testing exist.
If paternity of a child is in question, having a paternity test performed will provide you and the parties in question definitive answers surrounding your child’s parental identity. Naturally, you can wait until your baby arrives to handle this process. However, many people do not want to wait until their baby is born to establish paternity. If you choose to have prenatal paternity testing done you can choose from three different methods of DNA collection for your unborn child including chronic villi sampling (CVS), amniocentesis, and fetal cell/DNA.
If paternity of your child is in question either from the beginning or early on in your pregnancy you may choose to use chronic villi sampling as your DNA collection method. This type of prenatal paternity testing takes place between the 10th- 13th week of pregnancy. If you opt to use this method your doctor will need to collect a small sample of your placenta. The placenta is the membrane that surrounds a baby in-utero and it is their lifeline from conception to delivery. To collect a DNA sample using the CVS method your doctor will need to obtain a sample transcervically or transabdominally. Most experts believe the procedure is relatively safe. That said, some studies have shown a one percent rate of miscarriage with this procedure.
