You should have bone mineral testing if you have an increased risk of osteoporosis. Women aged over 65 and men aged over 70 are more likely to develop osteoporosis. Bone mineral density testing can also detect osteopenia, an intermediate stage of bone loss between normal bone density and osteoporosis. Your doctor may also suggest bone mineral density testing to monitor how your bones are responding to treatment if you have already been diagnosed with osteoporosis. Other reasons you may require BMD include: prolonged steroid use, early menopause, male hypogonadism (lower than usual testosterone).
