Shop - Ionized Calcium

The “Ionized Calcium” test measures the amount of free calcium in the blood that is not bound to proteins. Ionized calcium is the biologically active form of calcium in the body, essential for muscle contraction, nerve function, and blood clotting. This test is often used to assess calcium balance in critically ill patients or in cases of abnormal total calcium levels, kidney disease, parathyroid disorders, and certain cancers.
