Here is something interesting I learned from my doc today: There is a new DNA panel that tests for your tolerance and ability to metabolize most drugs. They do cheek swabs and send back a report that is pages long. They also give you a wallet card (printed by them--so it has some weight) that you can show in the ER or anyplace else when necessary. The card lists drugs that you should not be given. The company is Asperio. http://asperiolabs.com/pharmacogenomics/ So instead of trialing on a bunch of different possible drugs for a condition, your doc can select a medication in light of what the DNA test shows. Sound good to me! And for those of us with a history of reacting badly to medications, it could be a life saver.
