Mild hypercalcemia is defined as a total serum calcium of which range?

• A. 8.0 - 10.0 mg/dL
• B. 9.0 - 9.9 mg/dL
• C. 10.3 - 12.9 mg/dL
• D. 13.0 - 15.0 mg/dL

Answer: (C)

Total serum calcium has a reference range, typically about 8.5–10.5 mg/dL in most labs. Mild hypercalcemia means calcium is above the upper limit of normal but not markedly elevated. In many guidelines, that mild rise starts just above that upper limit and stays in a low-to-moderate range, roughly around 10.3–12.9 mg/dL. Values below the upper normal limit aren’t hypercalcemic, and very high values (often above about 13 mg/dL) indicate more severe hypercalcemia. So the range that begins just above normal and remains in the mild elevation zone best fits the concept, which is why it’s the correct choice. The other ranges are either normal or represent more extreme levels.
