During the production of this issue of On Demand, the CDC declared the official start to the flu season, the latest start in 25 years. Drs. Ellen Jo Baron and Fred Tenover have written an up-to-date review of molecular diagnostic methods for respiratory infections, including the Xpert Flu test which provides on-demand results for FluA/B and H1N1 novel 2009, all of which are circulating this flu season. As the science and practice of Precision Medicine evolves toward the ultimate goal — providing the right patients with the right doses of the right medication at the right time — the impact of molecular diagnostics has never been greater. In the article by Donna Wolk and Daniel Olsen, you will find an excellent overview of the Verification and Validation processes that underpin the basic credibility and reliability of the diagnostic results we furnish on a daily basis. We hope you will benefit from reading both articles in this issue.
