A bone density test is a type of x-ray. During the test images are taken of your lower back (spine), hip and forearm. A bone density test will show how dense these bones are. When a person has osteoporosis the bone is not as dense, and therefore weaker than it should be. A bone density test can help determine a diagnosis early, before a person has a bone fracture and can help determine the effects of treatment.
