Ethical Issues Associated With Direct-to-Consumer Genetic Testing.

Abstract

Direct-to-consumer genetic testing (DTC-GT) is becoming an increasingly profitable private enterprise that provides genetic testing kits directly to consumers. DTC-GT companies advertise themselves as a method for patients to take control of their own health and investigate their risk of diseases and conditions as well as look into their ancestry. The scope of practice of these companies continues to widen offering more services. Consumers may therefore have a relatively poor understanding of the services provided when purchasing these products. The testing methods utilised show some limitations, the consequences of which have the possibility of leading to harm to consumers. The result of the data gathered may instigate the formation of negative stereotypes from the public and reinforce existing ones towards a population that may have already been previously subjugated to unfair treatment. The controversy surrounding how data are utilised further impacts how many may engage in its use. This review aims to provide an overview of the services these companies purport to provide as well as highlight important ethical issues of the service such as quality of information, privacy concerns, negative psychosocial impact and the effect on clinical practice.
