Genetic testing: implications for professional nursing.

Scientific information emerging from human genome research has significant implications for the practice of professional nursing. Professional nurses assist individuals in making decisions about DNA studies, ensure that consent is informed before genetic testing, and help clients cope with genetic information after test results are known. Nurses with advanced education in genetics identify and counsel people who are candidates for DNA testing. Gene identification can have beneficial as well as harmful outcomes. Education is needed to prepare nurses for new roles regarding genetic testing.
