Because hypercalcemia can cause few, if any, signs or symptoms, you might not know you have the disorder until routine blood tests show a high level of blood calcium. Blood tests also can reveal whether your parathyroid hormone level is high, indicating that you have hyperparathyroidism.

To determine if your hypercalcemia is caused by an underlying problem, such as cancer or sarcoidosis, your doctor might recommend imaging tests of your bones or lungs.
