Quizplus · Accepted Answer

The T-score is a comparison between an individual's bone mineral density (BMD) and the mean score of a healthy 30-year-old female. A normal score would be within one standard deviation of the average 30-year-old female. A score greater than one standard deviation outside of the average would indicate low bone density, or osteoporosis.
