Prenatal Paternity Tests
Pregnancy is a wonderful and exciting experience. The situation may arise where it becomes necessary to find out the baby’s paternity prior to them being born. Where this is the case prenatal Paternity Testing can be done. This test has to be done by a well trained doctor. There is currently no home testing that is available for prenatal testing.
It is very important that a doctor is involved throughout the process because there are a number of factors that influences the foetuses health. So even though it may be important to the mother to determine paternity, the doctor will always consider the health of the child first. Also a prenatal paternity test is usually moderately invasive for both child and mother and involves DNA being taken. For the DNA to be taken, cells of the foetus will have to be disturbed. The procedure will not harm the child normally.
Before a prenatal paternity test is done your doctor will have to determine how advanced the pregnancy is. Once this is done, he will then decide on which type of prenatal paternity test is to be done and any possible complication that may arise from the procedure. If there is any sign of trouble the test will be postponed until after the child is born.
The sample for the test is usually taken using one of two extraction procedures. One method is the chorionic villi sampling which is normally done somewhere around the tenth to the thirteenth week of pregnancy. Going through the abdomen or the vagina, a sample of the placenta is obtained. The placenta is made up of a material containing the exact DNA as that of the egg cell. The other is performing an amniocentesis around the fourteenth and twenty-fourth week. Here a needle is inserted into the sac where the baby is growing and a bit of fluid is taken.
