What is gene testing?

Gene testing, also known as genetic testing or DNA testing, is a medical test that examines a person’s DNA to identify any changes or mutations in their genes. This type of testing can provide information about a person’s risk of developing certain diseases or conditions, as well as help diagnose genetic disorders. Gene testing can be done using a variety of methods, including blood tests, saliva tests, and cheek swabs. The results of the test can provide valuable information about a person’s health and can help inform medical decisions and treatment options.
