Calcium Free (Ionised), Serum

Free (ionized) calcium is the active form of calcium circulating in the blood that is not bound to proteins. It regulates muscle contractions, nerve impulses, and blood clotting. The test helps detect Calcium metabolism disorders. Active form of calcium: Free calcium is not bound to proteins and is biologically active, participating in vital physiological processes.
Muscle and nerve regulation: Free calcium is necessary for normal muscle contraction and nerve signal transmission.
Blood clotting: Ionized calcium plays a key role in the blood clotting process.
Diagnosis of disorders: The test helps detect calcium Metabolism issues related to parathyroid disorders, kidney disease, or metabolic abnormalities. This is the active form of calcium that is not bound to proteins and is available for physiological processes, such as muscle contractions, nerve signal transmission, and blood clotting. This test provides more precise information about biologically available calcium, especially in cases where blood protein levels are altered (e.g., in Liver, or kidney diseases).
