The information from a bone density test enables your doctor to identify where you stand within ranges of normal and to determine whether you are at risk for fracture. In general, the lower your bone density, the higher your risk for fracture. Test results will help you and your doctor decide the best course of action for your bone health. There are several different machines that measure bone density. Central machines measure density in the hip, spine and total body.
Peripheral machines measure density in the finger, wrist, kneecap, shin bone and heel.
