BMD (Bone Mineral Density) Interpretation

BMD results are expressed as a T-Score. The T-Score relates to a standard normal score (zero) and the patients results are compared to this standard. If bone loss is diagnosed the T-Score will be in the negative, anything above zero indicates healthy bone density. Scores can look like the following:
  • +1 to -1 means your bones are considered normal
  • -1 to -2.5 means you have osteopenia, or low bone density
  • -2.5 or lower means you have osteoporosis
  • Each decrease by one point indicates bone loss of 10 to 12 percent.
