Reasons Why Genetic Testing Is Important The body is quite complicated. 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. In addition, genes are a major determinant of a person’s health. Genetic research therefore plays an important role in the medical field. Genetic tests are carried out on the blood or other tissue samples of the subject. There are many reasons why genetic testing has become crucial in the modern medical world. Some of them are discussed below. Probably the most frequent use of DNA testing is when conducting paternity tests. For one reason or the other one may not be sure about the identity of their parents or whether a child is theirs. The DNA structure of parents usually has some similarities with that of their kids. This is the reason why parents and children have a lot in common and resemble each other. A DNA test performed on both the parent and the child can help confirm beyond reasonable doubt whether the child is the son or daughter of the parent. Thanks to genetic testing individuals have managed to find their lost relatives. Data from DNA tests can also be used in legal battles like child support cases. 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. A change in a person’s genes may also cause development of a disease. Genetic tests helps detect anomalies inside the persons genes which will help prevent, detect and treat diseases.
