ETHICAL ISSUES IN PRENATAL TESTING

Many ethical concerns raised by prenatal testing are based on the use and effects of genetic information in nonclinical contexts. Correct or incorrect beliefs about social uses of genetic information may limit the voluntariness of informed consent to prenatal testing. A qualitative study of persons predictively tested for Huntington's disease illustrates how the social context, in this case the family history of being at risk, affects the interpretation of the genetic information and alters relationships. This constitutes a risk of genetic testing. Prenatal testing also requires ethical analysis based on careful understanding of how social attitudes and nonclinical uses affect voluntariness and potential harm and benefits of testing. Investigators conducting research on prenatal tests share the responsibility to evaluate social attitudes toward at-risk persons, nonclinical uses of genetic information, and the social benefits and harm of such uses.
