A bone mineral density (BMD) test measures how much calcium and other types of minerals are in an area of your bone. This test helps your health care provider detect osteoporosis and predict your risk of bone fractures..
How the Test is Performed
Bone density testing can be done several different ways.
The most common and accurate way uses a dual-energy x-ray absorptiometry (DEXA) scan. DEXA uses low-dose x-rays. (You receive more radiation with a chest x-ray.)
How to Prepare for the Test
If you are or could be pregnant, tell your health care provider before this test is done.
