Genetic testing is used to look for any kind of changes in the genes which are also known as mutation or genetic variation sometimes. genetic testing is useful in many areas of medical care. For example, it can help you diagnose a genetic disorder, the results of genetic tests that are done by using blood or spit sample can tell you if you have any kind of genetic disorder or are at the risk of developing one in the future.
Genetic tests can also tell you about the chances of you developing cancer in the future. And since you and your family members all have similar DNA if your result shows that you are at risk of developing a certain genetic disorder your family might be in the danger of developing that genetic disorder too, so it can help you determine all the possibilities.
