What is an acceptable range for T-scores in healthy adults?

• A. Between -1.0 and +1.0
• B. Below -2.5
• C. Above 0.0
• D. Between -1.5 and +1.5

Answer: (A)

The correct answer indicates that an acceptable range for T-scores in healthy adults is between -1.0 and +1.0. T-scores are a key metric used in bone densitometry to assess bone mineral density (BMD) compared to a healthy young adult population. A T-score of 0 represents normal bone density, while a score between -1.0 and +1.0 suggests that the individual has normal or healthy bone density.

In this range, individuals have bone density levels that are not significantly lower than the average for their age group, which implies a lower risk of osteoporosis and fractures. Understanding T-scores is crucial for assessing and diagnosing bone health, as well as for determining appropriate preventive measures or treatments.

The other potential ranges mentioned do not align with established standards for healthy bone density. For instance, a T-score below -2.5 is indicative of osteoporosis, and values above 0.0 may suggest increased bone health but do not specify an acceptable range for normality. Additionally, the range between -1.5 and +1.5 expands the scope too broadly, as it includes values that may indicate bone density concerns. Hence, the most accepted clinical standards recognize the -1.0 to +
