What is a bone mineral density test? Is it painful?
A bone mineral density (BMD) test is the best way to determine your bone health. This test can identify osteoporosis, determine your risk for fractures (broken bones), and measure your response to osteoporosis treatment. The most widely recognized BMD test is called a dual-energy x-ray absorptiometry, or DXA test. The test is safe and painless, a bit like having an x ray, but with much less exposure to radiation. It can measure bone density at your hip and spine and takes only 15 minutes to complete. For a DXA test, you will be asked to lie on a table while a machine above you measures your bone density. Some private insurance plans will cover BMD tests ordered by your doctor. Medicare also may pay for a BMD test under certain circumstances for women and men age 65 or older. Your doctor and his or her office staff can help you determine if Medicare will cover a BMD test for you.
