This is unambiguously one to talk beside your doctor about. I provided some links near an overview of how they calculate bone density, but necessarily the results of your test are usually reported as a "T score" and "Z score."

The T score compares your bone density near that of healthy young at heart women. The Z score compares your bone density beside that of other people of your age, femininity, and race. In any score, a refusal number means you enjoy thinner bones than the standard. The more negative the number, the thinner your bones. A T ranking is within the common range if it is a positive number, or at smallest no more negative than -1.0. (For example, -0.5 is in the normal collection, although it is getting borderline.)

Your doctor will help you deduce the results.

A T score from -1 to -2.5 indicates the emergence of bone loss (osteopenia).
A T score below -2.5 indicates osteoporosis.
