A T-score of -1.0 indicates what?

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

Answer: (B)

A T-score compares your bone density to that of a healthy young adult and shows how much your bones deviate from peak bone mass. The scale falls into clear ranges: normal density is about -1.0 or higher, osteopenia ranges roughly from -1.0 down to -2.5, and osteoporosis is -2.5 or lower (with severe osteoporosis when there’s a fragility fracture). A T-score of -1.0 sits at the lower end of normal and into osteopenia, indicating some bone loss but not to the level of osteoporosis. Hence it’s labeled osteopenia. It’s not osteoporosis because the score isn’t -2.5 or lower, and not normal because the value is already below the normal threshold.
