Many Americans—and their doctors—seem to think that better health means more health care, including as many screening tests as possible. But many researchers are now questioning that notion, saying that some common screening tests are unproven and can not only waste your time and money but also cause more harm than good.
Instead, you should focus on tests proven to work. "When you reach into the life of someone who isn't sick and potentially trigger anxiety, further testing, and even invasive treatments, you better have a good idea that the test is effective and safe," says Mark Helfand, M.D., director of the Evidence-based Practice Center at the Oregon Health and Science University in Portland.
To help identify preventive practices that work, the government-sponsored U.S. Preventive Services Task Force reviews the evidence for and against screening tests and counseling recommendations. In Skip These Tests we discuss those that the Task Force has given a D rating, meaning that they failed the group's test. (The table lists those that Consumer Reports thinks most people should get, based on recommendations from various public-health organizations and our medical consultants.)
