What type of genetic testing is right for me?
Talk to a genetic counselor to learn about your options and determine what type of testing is right for you.
• Single-gene testing (also known as targeted genetic testing or targeted single variant testing) will examine the DNA of a single gene and look for any changes or mutations in that gene. This may be recommended for you if you have a known family history of a gene mutation. These tests are often used to confirm or rule out a specific diagnosis.
• Multigene panel testing is a type of genetic testing that is performed to look for mutations in several genes at one time. These panels are based upon your personal and family health history and may be recommended if you are at risk of a hereditary cancer syndrome that has more than one gene associated with it.
• Broad-based genetic testing simultaneously tests for hundreds of diseases. Exercise caution when considering broad-based testing—which is not individualized based on family history or personal risk—as it may pick up mutations for which risk is not known, or nothing can be done, which can result in more harm than good.
• Direct-to-consumer tests can be done at home by providing a saliva sample and sending it back to the company’s lab for analysis. They are primarily used to find family connections or discover one’s ancestry, but several do have health-based genetic testing components. Despite the ease of an at-home test, it’s a good idea to meet with a genetic counselor following testing, regardless of whether your test identifies a genetic mutation or not. Genetic testing with a genetic counselor or health care provider may need to be repeated to confirm any at-home test results.
