Genetic testing
WHAT: Genetic testing, also known as DNA testing, allows the genetic diagnosis of vulnerabilities to inherited diseases.
WHY: Doctors use genetic tests for several reasons such as finding out of people carry a gene for a disease that they might pass on to their children. And genetic testing can also screen embryos for disease.
HOW: Test results might help a person make life decisions, such as family planning or insurance coverage. A genetic counselor can provide information about the pros and cons of testing.
