A normal serum calcium level is 8-10 mg/dL (2-2.5 mmol/L) with some interlaboratory variation in the reference range, and hypercalcemia is defined as a serum calcium level greater than 10.5 mg/dL (>2.5 mmol/L). Hypercalcemia may be classified based on total serum and ionized calcium levels, as follows: 1  Mild: Total Ca 10.5-11.9 mg/dL (2.5-3 mmol/L) or Ionized Ca 5.6-8 mg/dL (1.4-2 mmol/L) 2  Moderate: Total Ca 12-13.9 mg/dL (3-3.5 mmol/L) or Ionized Ca 8-10 mg/dL (2-2.5 mmol/L)
