From a medical perspective, I advise people who are thinking about DTC genetic testing to think of it like the over-the-counter (OTC) medical tests available in many pharmacies. An OTC pregnancy test is designed to answer a focused question: whether or not a woman is pregnant. An OTC cholesterol test answers a similarly focused question. I tell people that DTC genetic tests very rarely return results that are medically actionable, unless originally done to answer a focused question about a rare genetic disease.
