Background provided by, one of many commercial for-profit testing providers:


The enzymes that are affected by your genes belong to a large family called CYP450. Just a few of the many CYP450 enzymes do most of the work required to metabolize the drugs we take. After a drug is metabolized, it is eliminated from the body. These enzymes are extremely important, because the effect they have on drugs can change – sometimes drastically – the effect that drugs have on us. Approximately 85 % of Americans have genetic variations that influence how these enzymes metabolize drugs.

Your unique profile for each of these enzymes has been identified. The YouScript¨ Personalized Prescribing System then developed a report to explain how each of your enzymes metabolizes drugs. The results of this test will not change in your lifetime. Each enzyme that was tested is categorized as follows:

In addition to describing how your enzymes metabolize drugs, your report also provides detailed information and prescribing recommendations about each of the drugs you are currently taking.
