Genetic testing involves studying the chemical language, or DNA, that controls your body’s functions. Genetic testing can reveal genetic anomalies that may result in illness or disease.
While genetic testing can be used to provide important medical information, it also has limitations. Just because someone is genetically predisposed to develop a specific disease, it does not always mean they will develop that disease. On the one hand, negative results don’t necessarily mean that you won’t already have the disorder.
Talking to your doctor about what you would do with the results of genetic screening is an important first step in the process.
