Hypercalcaemia ( British English) or hypercalcemia ( American English) is an elevated calcium (Ca) level in the blood. (Normal range: 8.7–10.4 mg/dL or 2.2–2.5 mmol/L.) It can be an asymptomatic laboratory finding, but because an elevated calcium level is often indicative of other diseases, a workup should be undertaken if it persists. It can be due to excessive skeletal calcium release, increased intestinal calcium absorption, or decreased renal calcium excretion.
