After you take a bone density test you usually receive two scores: a T score and a Z score. The T score is based on young adult women who have normal bone density. If your T score is more positive than-1, you have a healthy bone mass. If you score between-1 and-2.5 you have osteopenia, which means you are beginning to lose bone mass but do not yet have osteoporosis. If you score more negative than-2.5 you have osteoporosis.
