Genetic testing examines a person's DNA for the presence of genetic variants that may change his/her risk of a specific genetic disorder.
Research and clinical genetic testing differ mainly in the purpose of the test and the form of the results.
The goal of genetic research is the discovery of new variants that may influence people's tendency to suffer from a genetic disease
Overall results are usually published but individual results are not available to patients or their healthcare providers.
In clinical genetic testing the goal is to diagnose a genetic disorder based on the presence of known variants with a strong proven
role in the disorder
. Clinical results are sent to patients and their healthcare providers to help make decisions about the prevention,
diagnosis and treatment of their disease. Because of this, clinical genetic testing must be carried out in special CLIA-certified laboratories
that follow strict guidelines to ensure accuracy.
