Bone Density T-Score Calculator

The T-score is the standard measure for assessing bone density and diagnosing osteoporosis. It represents how many standard deviations your bone mineral density (BMD) differs from that of a healthy young adult of the same sex. T-scores are calculated from DEXA (dual-energy X-ray absorptiometry) scan results, the gold standard for measuring bone density. A T-score of -1 or above is normal, -1 to -2.5 indicates osteopenia (low bone mass), and -2.5 or below indicates osteoporosis. This calculator requires your BMD measurement from a DEXA scan along with reference values (typically provided in the scan report). Understanding your T-score helps assess fracture risk and determine whether treatment is needed. Important: This tool is for educational purposes - always discuss DEXA results with your healthcare provider for proper interpretation and treatment planning.
