![]() Most people reach their peak bone mass by age 30 after which, your body stops making new bone at the same rate it’s broken down. What causes low bone density?Īs you grow, your bones are constantly breaking down old bone and generating new bone material. For instance, the United State Preventive Task Force Service guideline states that there is insufficient evidence to recommend osteoporosis screening in men. Other national organizations have published different guidelines on osteoporosis screening. Your provider may also order a bone density measurement if you have reached a certain age and have risk factors for osteoporosis. Men and women older than 50 who have broken a bone recently.The National Osteoporosis Foundation recommends testing on the following schedule: Any findings from these tests should be confirmed with a DEXA scan. Portable machines, called peripheral devices, can measure bone density at your finger, wrist, or heel-but they usually aren’t as accurate as medical tests taken at the spine or hip. , a medical director at Imaging and Interventional Specialists in El Paso, Texas. “Other methods to measure bone density include ultrasound, quantitative computed tomography (QCT), and peripheral dual-energy X-ray absorptiometry (pDEXA),” explains Gethin Williams, MD, Ph.D. This makes it possible to catch osteoporosis in its early stages,” Dr. “Unlike ordinary X-rays, DEXA scans can measure tiny losses in bone density. A DEXA scan is a quick and painless procedure that is very accurate at detecting bone loss. What is a bone density test?īone density is most commonly measured by a test called a DEXA scan (also called a DXA test), which uses X-rays to measure the amount of bone mineral, most commonly in your hips and lower spine. To prevent this, your healthcare provider may order a bone density test, or bone density scan, if you meet certain criteria. People often don’t have any symptoms until they break a bone. ![]() It’s possible to have weak bones without even knowing it. “Lower bone mineral density increases your risk of fracture.” “The higher your bone mineral density is, the stronger your bones are,” says Ellen Johnson MD, a board-certified radiologist in North Andover, Massachusetts. Bone density, or bone mineral density, refers to the amount of calcium and other minerals in your bone per volume measurement. Aging and certain medical conditions can weaken bones, resulting in low bone mass or low bone density. They help you move and protect your internal organs from injury. Having strong bones is important to your health. Those with unsettling bone density scores should rest assured that osteoporosis treatment is possible and available, and better yet, the early stages of osteopenia can be reversed before they worsen into osteoporosis.What is a bone density test? | Causes and risk factors | Bone density test preparation | Prices | Bone density test results | Osteopenia vs. Correct interpretation of the two bone density test scores, T-scores and Z-scores, is vitally important for women monitoring bone loss throughout and past the menopausal transition. Thanks to medical advancements, preparing for a bone density scan test is easy, painless, and takes virtually no effort. Also, medications might be prescribed to prevent further bone loss and reduce the risk of fracture.įor advanced stages of osteoporosis, their doctor may prescribe osteoporosis medications, and repeat bone density tests will be pursued to monitor treatment effectiveness. Women with lower BMD but not yet osteoporosis may wish to pursue additional testing with a specialist to verify bone mineral density scores. Treatment depends upon the stage of osteoporosis. What Do I Do If I Have A Low Bone Mineral Density Score? If one's Z-score is abnormally skewed, this could represent an external factor aside from aging that is causing atypical bone loss. The osteoporosis Z-score, on the other hand, represents a woman's bone density results in comparison to a person of her age, sex, weight, and ethnicity. Therefore, your doctor will look at your lowest T-scores to diagnose osteoporosis. For example, a BMD T-score of -5.5 is lower than that of -2.5, and an osteoporosis score of -1.0 is lower than that of 1.0. In general, the lower the T-score, the lower your bone density. ![]() Low Bone density ( Osteopenia): Between -1 and -2.5.The following ranges should be used to interpret T-scores for osteoporosis: 1 Bone Density T-ScoreĪ T-score for bone density reflects how much your bone density is higher or lower than that of a healthy, 30-year-old adult. ![]() The results of a bone density test are usually expressed as two bone density test scores: T-score and the Z-score. Over time, you can track bone density scores to see if they are improving, stagnant, or worsening, thus helping judge treatment effectiveness as well. The bone mineral density test estimates the density of your bones and your risks of breaking a bone before it happens. ![]()
