For the results of your scan, you’ll get a T-score. It shows how much higher or lower your bone density is than that of a healthy 30-year-old, the age when bones are at their strongest. The lower your score, the weaker your bones are:
Sometimes doctors will give you another DXA scan result -- a Z score. It compares your bone density to a normal score for a person of your same age and body size.
- T-score of -1.0 or above = normal bone density
- T-score between -1.0 and -2.5 = low bone density, or osteopenia
- T-score of -2.5 or lower = osteoporosis
