A bone-density result comparing your bone to that of a healthy young adult.
The T-score from a DEXA scan compares your bone mineral density with that of a healthy young adult of the same sex. A T-score of -2.5 or lower generally indicates osteoporosis.
A T-score between -1.0 and -2.5 falls in the osteopenia range, while a score of -1.0 or above is considered normal.
