What does the DEXA test measure?

• A. Bone mineral density and fracture risk
• B. Kidney function
• C. Infection markers
• D. Liver enzymes

Answer: (A)

Bone mineral density assessment is what the DEXA scan provides. It uses two low‑dose X‑ray beams to estimate how dense the bones are, usually focusing on the spine and hip. The results are given as a T-score and a Z-score: a lower T-score means weaker bones and higher fracture risk, with osteoporosis typically defined as a T-score of -2.5 or lower and osteopenia between -1 and -2.5. This information helps diagnose osteoporosis and guide treatment decisions. DEXA does not assess kidney function, infection markers, or liver enzymes—those are measured by other tests. The test is quick, noninvasive, and involves very little radiation.
