Calcium Levels in the Body: Factors, Symptoms, and Testing

Factors affecting calcium levels in the body include dietary intake, absorption efficiency, phosphate levels, and hormone activity. Hypocalcemia and hypercalcemia are conditions of low and high blood calcium levels, respectively, with various causes and symptoms. Calcium testing helps diagnose issues with parathyroid glands, kidney function, cancer, bone health, and more. A bone mineral density test assesses calcium levels in bones. Proper preparation is required for accurate test results.
