When interpreting a T-score, what is necessary for diagnosis?

• A. Choosing the average T-score among tests
• B. Using the highest recorded T-score
• C. Using the lowest T-score from measurements
• D. Considering the patient’s age and other factors

Answer: (C)

In the context of bone densitometry and interpreting T-scores, the focus is on identifying the T-score that best reflects the patient's bone mineral density (BMD) in relation to the expected BMD of a healthy young adult of the same gender. The T-score indicates how much the patient's bone density deviates from this normative value. Using the lowest T-score from measurements is appropriate for diagnosis because it provides a conservative estimate of the patient's bone health. The lowest T-score is crucial, as it indicates the site with the most severe reduction in bone density, which is pivotal in assessing the risk of osteoporosis and potential fractures. This method ensures that the clinician considers the worst-case scenario, which is essential for effective diagnosis and subsequent treatment planning. In contrast, choosing the average T-score may mask significant areas of bone loss, while using the highest recorded T-score would not adequately reflect the areas of greatest concern. Additionally, considering the patient's age and other factors is important for a comprehensive assessment, but this option does not directly address the T-score interpretation necessary for diagnosis itself. Therefore, relying on the lowest T-score effectively guides clinical decision-making regarding the patient's bone health status.
