Last week, Dallas Mavericks owner Mark Cuban caused quite a stir on Twitter by suggesting that people, if they could afford it, get quarterly bloodwork to establish a baseline of their own health. A big failing of medicine, he wrote, is that “we wait till we are sick to have our blood tested and compare the results to ‘comparable demographics.’

” While that idea may seem logical, medical researchers have long cautioned that more testing is not a recipe for better health. I and others, including many doctors, countered Cuban’s views, saying they could produce dangerous outcomes for patients. (You can find my summary here and here.)
