Bone Density Testing Home A-Z Health Information Health Library A-Z Bone Density Testing Overview The weight of our entire body is borne by the bones that make up our skeletal system. Every movement needs muscles that move the bones to allow varied range of movements. The strength of the bones, particularly in the important weight bearing areas, is important in preserving health and quality of life. The measurement of bone density allows us to learn about the risks of bone fracture. For several reasons, some people have reduced bone density, which increases the risk of fractures and can take away the ability to lead a healthy and fulfilling life.The bone density is measured using a technique called Dual Energy X Ray Absorptiometry (DEXA). This technique can measure several components comprising the body and bones, which allows one to decide risk of having fractures and whether specific treatment is required to improve the strength of the bones. What can DEXA testing do? Tell you if you have reduced bone densityPredict you risk of having a fracture in the futureMeasure if the bone density is improving or getting worseMonitor treatment outcomes Who Should Be tested? Anyone with a fracture and who the doctor may suspect to have reduced bone densityWomen after menopause, particularly if they have risk factorsMen over 70 years of age or earlier if they have certain risk factorsPatients with an X-ray of the spine showing a bone with fracture or density lossPatients with back painPatients with height loss When should the test be repeated? If you are on medicines for correcting bone density, the test should be repeated once a year or once every two years at the very least. Your doctor will decide how often you need testing depending on your condition.
