Reasons Why Genetic Testing Is Important The human body is very intricate. It is made up billions of cells which contain the basic unit of our identity known as deoxyribonucleic acid or more commonly known as DNA. DNA is made up of genes which determine the majority of our bodies’ special qualities. The genes also play an important role in the health of the people. Genetic research therefore plays an important role in the medical field. These tests are carried out on tissue samples or the blood of the subject. There are many reasons why genetic testing has become crucial in the modern medical world. A number of them are discussed below. Probably the most frequent use of DNA testing is when conducting paternity tests. For one reason or another a person may need to confirm whether a child is theirs or they might not be sure about the identity of their parents. The DNA of children has many similarities with that of their parents. This is the reason why parents and children have a lot in common and resemble each other. Conducting a DNA test on the child and the parent can help confirm whether the child is their parent’s son or daughter. As a result of genetic testing many people have been able to find their long lost relatives. Information from DNA tests has also been used in legal battles for instance in child support suits. Another importance of genetic tests is in detecting diseases which a person may be suffering from or at risk of suffering from. A lot of illnesses have roots in our genes. Some illnesses are passed down through genes from parents to their kids. An alteration in a person’s genetic structure may lead to development of an illness. Genetic testing helps detect anomalies within the person’s genetic structure which in turn helps detect, prevent and cure ailments.
