Oct 3, 2018 · Your bone density can be compared to that of a healthy young adult. The difference is calculated as a standard deviation (SD) and is called a T score. Standard deviation is a measure of variability based on an average or expected value.
Oct 15, 2024 · Your bone density can be compared to that of a healthy young adult. The difference is calculated as a standard deviation (SD) and is called a T score. Your score will tell you if your bone density is normal, if you have osteopenia or if you have osteoporosis.
A T-score is the difference between your bone mineral density and 0, which is the bone mineral density of a healthy young adult. The lower your T-score, the higher your risk of bone fracture. What is a Z-score?
Jul 7, 2023 · T-scores and Z-scores evaluate bone density in relation to a healthy young adult. T-scores compare the bone density of older adults to that of younger adults, while Z-scores compare the bone ...
Bone mineral density tests measure the solidness and mass (bone density) in the lumbar spine, hip, and/or wrist, which are the most common sites of fractures due to osteoporosis. Other tests measure bone density in the heel or hand. These tests are performed like X-rays. They are painless, noninvasive, and safe.
A bone density test determines the bone mineral density (BMD). Your BMD is compared to 2 norms—healthy young adults (your T-score) and age-matched adults (your Z-score). First, your BMD result is compared with the BMD results from healthy 25- to 35-year-old adults of your same sex and ethnicity.
Your bone density measurements will be compared with the bone density of a young healthy adult or an adult of your own age, gender and ethnicity. Find out more about how bone density scans are performed. How safe are bone density (DEXA) scans. Bone density scans are very safe.
