Identifying DNA Abnormalities Through Genetic Testing Essay -- presymp

Genetic testing involves examining an individuals DNA and identifying abnormalities within the chemical makeup of specific structures. It, essentially, maps the persons genome and roll in the hay be interpreted to predict future issues. By analyzing the chromosome, genes, and even authorized proteins, physicians and researchers can find changes that lead to inheritable disorders. These changes can lead to possible diagnosis or cure for the disorder in question. In most cases, genetic testing is used to cook the probability that an individual will develop a certain disorder. It is not used to specifically diagnose a disorder, as there are no techniques that are 100% accurate. Genetic testing techniques do institutionalize good evidence to confirm a physicians findings, but it is not the first act a physician takes to diagnose a disorder. It can narrow a search or rule give away a specific disorder very confidently, but making a diagnosis base solely on genetic testing is not a n action that a qualified medical professional would consider.There are many types of genetic tests that are administered to the adult population. The more commonly used genetic tests are paternity tests, genealogical tests, and forensic testing. They are quite self-explanatory paternity tests are to determine relatedness of 2 subjects, genealogical tests are used to formulate a heritage or ancestry, and forensic testing is used to identify or rule out a person that has been charged with a crime. Other genetic tests include presymptomatic testing, used to determine the risk someone has to developing a genetic disorder, diagnostic screening, used to rule out or identify a suspected condition, and carrier screening, used to determine if an individual carries one copy of a gene mutati... ...sts?
