Blood Calcium Levels

Blood calcium levels refer to the amount of calcium — a vital mineral — circulating in your bloodstream. Calcium is crucial for various functions, including building strong bones and teeth, muscle contraction, nerve transmission, and blood clotting. The body tightly regulates calcium levels through hormones like parathyroid hormone and calcitonin, maintaining a normal range of about 8.5 to 10.2 mg/dL. Abnormal levels can indicate health issues: high calcium (hypercalcemia) may cause weakness or kidney problems, while low calcium (hypocalcemia) can lead to muscle cramps or tingling. Proper calcium balance is essential for overall health.
