Imagine a world where your doctor could help you avoid sickness, using knowledge of your genes as well as how you live your life. Or where he would prescribe drugs he knew would work and not have debilitating side-effects.
Such a future is arriving faster than most realise: genetic tests are already widely used to identify patients who will be helped or harmed by certain drugs. And three years ago, in the face of a torrent of new scientific data, a number of new companies set themselves up to interpret this information for customers. Through shop fronts on the internet, anyone could order a testing kit, spit into a tube and send off their DNA—with results downloaded privately at home. Already customers can find out their response to many common medications, such as antivirals and blood-thinning agents. They can also explore their genetic likelihood
A. identify customers’response to common medications
B. diagnose customers’ health state in the future
C. judge customers’ genetic inclination to some diseases
