Overview

About This Test

Calcium plays a role in far more than bone health. It's essential for nerve signaling, muscle contraction, heart rhythm, and blood clotting. This test measures the calcium circulating in your blood, a small fraction of your body's total calcium, most of which is stored in bone and teeth. Results outside the normal range can point to a variety of conditions affecting the bones, kidneys, thyroid, or parathyroid glands, so this test is often used both for general health screening and to help investigate symptoms like muscle cramps, numbness, or fatigue.
