A Dexa T-score less than -2.5 corresponds to which category?

• A. Osteoporosis
• B. Osteopenia
• C. Normal
• D. Severe osteoporosis

Answer: (A)

A DEXA T-score shows how your bone mineral density compares to a young healthy reference group, expressed in standard deviations. The threshold system places a T-score of -2.5 or lower in the osteoporosis range. So a T-score below -2.5 indicates osteoporosis. Severe osteoporosis is a subset defined when osteoporosis is present plus a fragility fracture; since no fracture is mentioned here, the category described by a T-score under -2.5 is osteoporosis. The other possibilities—normal or osteopenia—reflect higher T-scores and do not fit values below -2.5.
