The invention of various genetic-testing procedures has taken the world by storm. Among the various techniques, DNA profile analysis is worth mentioning. Since, it is considered a very complicated process, it is carried out by professionals. This technique allows us to take an accurate look into an individual's parentage as well as determine weakness and susceptible towards any genetic diseases. This test is usually done by taking a DNA sample of the individual through hair, blood, skin or amniotic fluid. The DNA profile analysis is done once the sample is collected. The analysis, along with the patient's health record and family history, can result in several diagnoses. There are several type of such analysis to confirm various illnesses. One such test is the chromosomal analysis. This test is performed to verify whether a newborn is suffering from genetic disorder like congenital hypothyroidism,etc. Besides this test, carrier testing identifies whether an individual is a carrier of gene mutation or not. If both parents are carriers of gene mutation, the child is at risk of suffering from genetic disorder. The technique of DNA profile analysis has been a life saver for several individuals. With the help of this test, any type of genetic disorder can be identified which can be treated at the initial stage. This technique has also assisted law and enforcement department to capture criminals for their wrong doings. It has also helped to determine biological relationships and to rule out innocent victims. The prenatal paternity test is also a type of DNA profile analysis. This test is done to determine paternity of a child. It is usually carried out when the mother of the child has more than one partner. This test is also done when the supposed father is refusing to accept the child as his. Since this test is done before the baby is born, it is imperative to consult a doctor. The physician will check the vitals of the mother and the foetus and then determine whether the test can be carried out or not. If there is even a slight risk to the foetus when doing this test, the doctor will advice the parents to do the test after the baby is born. If the prescribed physician feels that the foetus is not at any risk when performing the prenatal paternity test, he will perform the test. In this procedure, the DNA of the child and the supposed father is compared. This is because a child inherits DNA from both his parents. The physician carries out this test by choosing one between the two methods. They are Chorionic Villus Sampling and Amniocentesis. In the Chorionic Villus method, the DNA sample is collected from the walls of the mother's uterus. In this prenatal paternity test, the sample is collected by inserting a needle to the womb. Besides this, in the amniocentesis method of the prenatal paternity test, the doctor will insert the needle through the abdomen of the pregnant mother into the uterus. The needle is used to draw out a sample of amniotic fluid which surrounds the foetus. The fluid contains the DNA of the baby which can be used to carry out the prenatal paternity test.
