What is the typical decimal place for a T-score measurement?

• A. 1
• B. 2
• C. 3
• D. 0

Answer: (A)

The T-score measurement in bone densitometry typically reports to one decimal place. T-scores are calculated based on the standard deviations from the mean bone density of a healthy young adult population. This level of precision is necessary for clinicians to evaluate and interpret bone density results effectively, as small differences can have clinical significance when assessing an individual's risk for osteoporosis or fractures. Presenting the T-score with one decimal place allows for a clear representation while not overcomplicating the data with excessive precision, which might not offer additional clinical insight. This standard helps ensure that the results remain easily understandable and applicable in clinical decision-making processes.
