Did you know that your unique genetic profile can determine how your body processes certain medications? For some people, they may metabolise drugs too quickly and as a result, get little or no benefit from a particular medication. For other people, they may metabolise medications too slowly and as a result, have an increased risk of side effects. Genetic testing can help to personalise your treatment by using genetic information to customise drug therapy and the doses that work best for you. As your DNA does not change, the testing only needs to be performed one time.
