However, there are also many challenges to be met, including the herculean task of ensuring that the information provided by such tests is scientifically sound and, ideally, medically actionable. We consider recent events in DTC testing and suggest a "thought experiment" of an approach that could ultimately meet the needs of patients, providers and regulatory authorities.
