In the past, osteoporosis could be detected only after a bone fracture. By that time, it is too late and your bones could already be quite weak. A bone density test makes it possible to know your risk of fracture before the fact.
A bone density test is a non-invasive test that uses X-rays to determine if you need to improve your bone health. The bones that are most commonly tested are usually the hip and spine.
Bone density tests are not the same as bone scans as they require an injection beforehand and are usually used to detect fractures and other abnormalities in the bone.
Regardless of your sex or age, your doctor may recommend a bone density test. Bone density tests are easy, painless and virtually no preparation is needed.
