In bone metabolism assessment, which minerals are commonly measured?

• A. Urea nitrogen and creatinine
• B. Calcium and phosphorus
• C. Aspartate aminotransferase and alanine transaminase
• D. Sodium and potassium

Answer: (B)

The main idea is that bone health is assessed by looking at minerals directly involved in bone structure. Calcium and phosphorus are the minerals that make up the mineral component of bone (hydroxyapatite) and their levels reflect bone mineralization and turnover. Measuring them helps identify issues like disorders of mineral metabolism, osteoporosis, or osteomalacia, and they are influenced by hormones such as parathyroid hormone and vitamin D, as well as kidney function. The other options focus on functions unrelated to bone mineral content: urea nitrogen and creatinine gauge kidney function, liver enzymes indicate liver health, and sodium and potassium are general electrolytes not specific to bone metabolism.
