A T-score is a measure used in bone density tests to assess the risk of osteoporosis and fractures. Specifically, a T-score is the difference between your bone mineral density and the bone mineral density of a healthy young adult. The reference indicates that a lower T-score signifies a higher risk of bone fracture (01-May-2023).
In essence, it tells you how your bone density compares to that of a healthy 30-year-old adult. It is a standard deviation measurement, with each standard deviation below 0 indicating a greater risk.
Here's a breakdown:
- The T-score is a key indicator derived from a bone density test, usually a DEXA scan (dual-energy X-ray absorptiometry).
- It is not your actual bone mineral density, but rather a comparison to a healthy young adult.
- Lower T-scores correspond to lower bone density and a higher risk of fracture.
