The top 5 tests you probably don't need, from the October 2013 Harvard Health Letter

Some health tests, such as colonoscopies and cholesterol checks, are wise preventive measures. Others aren't, and may be unnecessary, reports the October 2013 Harvard Health Letter. "I think we're doing too much screening," says geriatrician Dr. Suzanne Salamon, an instructor at Harvard Medical School.

Screening means checking seeming healthy individuals for hidden disease. Sometimes it finds a problem. More often it leads to the discovery of harmless variations of normal body parts, which then leads to expensive, anxiety-producing, and often painful testing and unnecessary procedures—none of which would have been needed without the initial test.

So which tests should be avoided? Harvard experts say that for individuals who don't have any symptoms or family history of a particular ailment, it can be a good idea to skip the test that screens for it. Five tests that can often be skipped include

  • electrocardiograms
  • whole body CT scans
  • coronary calcium scores
  • tuberculosis skin tests
  • and low-dose CTs for lung cancer

It's important to talk with a doctor, though, before making the decision to forego a screening test.
