What is Genetic screening?
[[File:Historic cost of sequencing a human genome.svg|thumb|350px|Total cost of sequencing a human genome as calculated by the [[National Human Genome Research Institute|NHGRI]]]] '''Genetic screening''' finds out [[genetic]] susceptibility to a particular disease. Genetic testing identifies differences in [[chromosomes]], genes, or proteins.<ref>{{cite web |url=http://www.ghr.nlm.nih.gov/handbook/testing/genetictesting |title=What is genetic testing? - Genetics Home Reference |publisher=Ghr.nlm.nih.gov |date=2011-05-30 |accessdate=2011-06-07 |archive-date=2006-05-29 |archive-url=https://web.archive.org/web/20060529002711/http://ghr.nlm.nih.gov/handbook/testing/genetictesting |url-status=dead }}</ref> It allows the [[Genetics|genetic]] [[medical diagnosis|diagnosis]] of vulnerabilities to inherited [[diseases]]. It can also be used to find out a child's parentage (genetic mother and father). Genetic screening in a broader sense includes [[biochemical]] tests for the possible presence of genetic diseases, or mutant forms of genes associated with increased risk of developing genetic disorders. Most of the time, testing is used to find changes that are associated with inherited disorders. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a [[genetic disorder]]. Several hundred genetic tests are currently in use, and more are being developed.<ref>{{cite web|url=https://www.nlm.nih.gov/medlineplus/genetictesting.html |title=Genetic testing: MedlinePlus |publisher=Nlm.nih.gov |accessdate=2011-06-07}}</ref><ref>{{cite web |title=Definitions of genetic testing |work= (Jorge Sequeiros and Bárbara Guimarães) |publisher=EuroGentest Network of Excellence Project |date=2008-09-11 }} [http://www.eurogentest.org/index.php?id=657] {{Webarchive|url=https://web.archive.org/web/20140808131023/http://www.eurogentest.org/index.php?id=657 |date=2014-08-08 }}</ref> Since genetic testing may open up [[wikt:ethical|ethical]] or psycholog
