How you prepare

By Mayo Clinic Staff

Bone density tests are easy, fast and painless. Virtually no preparation is needed. In fact, some simple versions of bone density tests can be done at your local pharmacy or drugstore.

If you're having the test done at a medical center or hospital, be sure to tell your doctor beforehand if you've recently had a barium exam or contrast material injected for a CT scan or nuclear medicine test. Contrast materials might interfere with your bone density test.
