The Bone Mineral Density Test (also known as dual-energy X-ray absorptiometry) is a method used to diagnose osteoporosis. Here, the body will be x-rayed twice very quickly – usually the lower spine and the hips.
The bone mineral density will be calculated and compared against the values of the population average or compared against the relevant age group. If your T-value lies below the population’s average, as defined by the WHO, then osteoporosis could be present and your risk of breaking or fracturing bones is raised.
Please stop taking calcium supplements around two days before the test so that the results are not falsified. The test itself only takes a few minutes.
