Personalized Medicine: Genetic Diagnostics Technologies


Published on

As medical understanding of the genotype/phenotype correlation of a disease becomes clearer, genetic testing can be expected to become a mainstay in the clinical setting. While the application of genetic testing to the clinical setting is very much in line with the larger medical goals of preventative and personalized medicine, there are many unanswered questions with regard to genetic testing.
