DNA tests

Direct-to-consumer genetic testing

Direct-to-consumer (DTC) genetic testing (also called at-home genetic testing) is a type of genetic test that is accessible directly to the consumer without having to go through a health care professional. Usually, to obtain a genetic test, health care professionals such as physicians, nurse practitioners, or genetic counselors acquire their patient's permission and then order the desired test, which may or may not be covered by health insurance. DTC genetic tests, however, allow consumers to bypass this process and purchase DNA tests themselves. DTC genetic testing can entail primarily genealogical/ancestry-related information, health and trait-related information, or both. Genetic testing has been taken on by private companies, such as 23andMe, Ancestry.com, and Family Tree DNA. These companies will send the consumer a kit at their home address, with which they will provide a saliva sample for their lab to analyze. The company will then send back the consumer's results in a few weeks, providing a breakdown of their ancestral heritage and possible health risks that accompany it.
