Understanding Your Bone Health Results
T-score
Compares your bone mineral density to the average healthy young adult of the same sex. Used to diagnose osteoporosis.
Z-score
Compares your bone mineral density to what is typical for someone of your age, sex, and size. Useful for identifying if bone loss is unusual for you.
Diagnostic Categories (based on T-score)
- Normal: T-score –1.0 or above
- Osteopenia (low bone mass): T-score between –1.0 and –2.5
- Osteoporosis: T-score –2.5 or lower
Fragility Score
A unique REMS measure of bone quality and resilience. Expressed as a score from 0–100: the lower the number, the better the bone quality and structure. This adds an important layer of information beyond bone density alone.

T-score shows low bone density and within the osteoporosis category. However, the Z-score is within the normal range, showing bone density is normal relative to the patient’s age.

Excellent Fragility Score showing the bone is tough and has brilliant structure.

Adam Pack’s scan shows a borderline T-score, indicating osteopenia. Z-score is also slightly below expected, suggesting bone density is a little low for his age.

Fragility Score is moderate, indicating bone structure is adequate but with some reduction in resilience compared to optimal bone quality.

Z-score shows normal bone density for age. T-scores can't be used as under the age of 50.

Very low Fragility Score showing that the bone is tough and has excellent microarchitecture.
