BMD test; Bone density test; Bone densitometry
Normal Values
The results of your test are usually reported as a "T score" and "Z score."
- The T score compares your bone density with that of healthy young women.
- The Z score compares your bone density with that of other people of your age, gender, and race.
In either score, a negative number means you have thinner bones than the standard. The more negative the number, the thinner your bones. A T score is within the normal range if it is -1.0 or above.
Your doctor will help you understand the results.
What abnormal results mean
- A T score from -1 to -2.5 indicates the beginning of bone loss (osteopenia).
- A T score below -2.5 indicates osteoporosis.
