Molecular genetic test identifies the variations in genes, chromosomes or protein with the goal to identify a suspected genetic condition. Genomic technologies are reaching the point of being able to discover genetic variation in patients with high precision and reduced rate, offering the promise of fundamentally altering medicine. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder. More than 1,000 genetic tests are currently in use, and more are being developed. Genetic testing is voluntary. Because testing has benefits as well as limitations and risks, the decision about whether to be tested is a personal and complex one.
