Genetic testing for medications is becoming very en-vogue lately, with an insurgence of laboratories offering testing that identifies several genetic markers. These markers can predict how an individual will react with a certain medication. Sounds great, doesn’t it? Before you get a prescription from your doctor, he or she might be able to predict whether you are more or less likely to suffer a side effect, or whether a different medication may be more effective. The goal is to tailor the drugs and the dosages to your personal genetic make up.
