How Long For Results?

You'll get the results within a few days. The results will include two scores, the T-score and the Z-score. The T-score measures your bone density compared with the average values in young adults of the same race and sex. The Z-score shows how your bone density compares with that of people your own age, race, and sex. A positive T-score means your bones are stronger than the average in a young adult, and a negative score means that your bones are weaker. If you have a T-score that is between -1.0 and -2.5, you have osteopenia. If it is below -2.5, you have osteoporosis.
