Genetic screening might be able to: 1 Tell you how effective certain lifestyle interventions will be for you. 2 Identify a rare disease. 3 Show risk of future disease, such as arrhythmias, cancers, heart failure, Alzheimer’s, aneurysms and strokes, Type 2 diabetes, etc. 4 Show current diseases: However, be aware that some associations between gene variants and diseases are based on older genetic mapping systems, so be prepared to do some research. 5 Identify diseases that you carry but which don’t affect you: In other words, identify carrier status of recessive traits, such as hemophilia. Couples can use genetic screening to predict the potential diseases and traits of their offspring.

Genetic testing looks for changes, sometimes called mutations or variants, in your DNA. Genetic testing is useful in many areas of medicine and can change the medical care you or your family member receives. For example, genetic testing can provide a diagnosis for a genetic condition such as Fragile X or information about your risk to develop cancer. There are many different kinds of genetic tests. Genetic tests are done using a blood or spit sample and results are usually ready in a few weeks. Because we share DNA with our family members, if you are found to have a genetic change, your family members may have the same change.

DTC test results can be used to make decisions about lifestyle choices or provide issues to discuss with your doctor. However, DTC tests cannot definitely determine whether or not you will get a disease and should not be used alone for decisions about your treatment or medical care.
