Genetic testing and screening in adulthood and at a prenatal state is a strong ethical debate of the society. According to Chadwick (1994), there is a difference between genetic testing and screening. Although the two expressions are usually used as synonyms, it is important to clear the confusion in the beginning of analyzing the ethical debate. Screening should only be used for the diseases of “high spontaneous mutation”, and there is no family history indicating that the condition would be present. Testing, however, is applied on large populations to identify risk factors and the purpose is mainly diagnostic.
