Benefits of Genetic Testing The human body is very complex. The human body consists of countless cells which contain the basic unit of humanity’s identity commonly known as DNA or deoxyribonucleic acid. DNA is made up of genes which determine most of the unique characteristics of our bodies. The genes also play an important role in the health of the people. In the modern medical world, genetic research plays an important role. Genetic tests are carried out on the blood or other tissue samples of the subject. Genetic tests have become vital in the modern world for a number of reasons. 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 structure of parents usually has some similarities with that of their kids. That is why most kids resemble their parents’ features. Conducting a DNA test on the child and the parent can help confirm whether the child is their parent’s son or daughter. Genetic testing can help people 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 disorders are also passed down to children through genes from their parents. An alteration in a person’s genetic structure may lead to development of an illness. Genetic tests helps detect anomalies inside the persons genes which will help prevent, detect and treat diseases.
