Test Name: Bone Mineral Density Alternate name: BMD test, Bone density test, Bone densitometry, DEXA scan, DXA, Dual-energy x-ray absorptiometry Test significance: A Bone mineral density (BMD) test uses X-rays to measure how much of calcium and other bone minerals are packed into a segment of bone. The bones that are most commonly tested are in the spine, hip and forearm. The higher your bone mineral content, the denser your bones are. And the denser your bones, the stronger they generally are and the less likely they are to break.
The prevalence of osteoporosis in Indian women aged 30-60 years is 29%- a disease that causes bones to become more fragile and more likely to break. Although osteoporosis is more common in older women, men also can develop the condition.
A BMD test at Suburban Diagnostics provides guidelines to help identify the decrease in bone density, to determine risk of fracture, monitor osteoporosis.
BMD test results are estimated on the basis of:
T Score: The patient’s bone mineral density as compared to the peak bone mass in normal young adult.
A score of 0 means BMD = norm of a healthy young adult
The diagnosis of osteoporosis or low bone mass is based on T-score
Z-Score: The patient’s bone mineral density as compared to the peak bone mass in age-sex matched adult.
Z – score is useful for determining whether an underlying disease or condition is causing bone loss.
