Pharmacogenomic testing: knowing more, doing better.

The clinical uptake of pharmacogenomic (PGx) testing and genotype-based prescribing has been disappointingly slow even though research on PGx is thriving. A recent survey on the adoption of PGx testing by US physicians suggests that this trend may start changing for the better. Acquiring more knowledge of PGx tests and their clinical significance during graduate and postgraduate education will enable physicians to make better use of the available and upcoming PGx diagnostics in clinical practice.
