“Researchers are alleging that tailoring medication to a person’s DNA could help reduce adverse effects by up to 30%. The study could see the piloting of medical “smart cards” expedited in Liverpool and Manchester and expanded to the rest of the UK if successful.

The study, published in The Lancet is the first time genetic profiling has been used for tailoring drug prescriptions. The scheme is being billed as a way to cut hospital admissions from unwanted side effects, which cost the National Health Service about £1 billion annually.

The study involved 7,000 people from seven European countries. In the UK, it was conducted by experts at the University of Liverpool, where they used DNA profiling to tailor 39 common prescriptions for a wide range of medical problems including heart disease, cancer, and mental illness.”
