Bone mineral density test

Alternative Names: BMD test; Bone density test 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. Text Continues Below 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 a positive number, or at least no more negative than -1.0. (For example, -0.5 is within the normal range, although it is getting borderline.) 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.
