DXA stands for “Dual-energy X-ray Absorptiometry” (Do-uhl en-er-gee x-ray ab-sorp-tee-om-uh-tree). That’s a mouthful. Luckily, the test is easier to do than to say. This is a test to see how strong your bones are. The test uses X-rays to see inside the muscles and bones in your body. X-rays are a form of energy you can’t see. The test also helps doctors figure out how much muscle you have, and how much body fat. You will be asked to lie on a table. You will need to be very still for a few minutes. The machine will take pictures of your muscles and bones. You won’t feel anything.
