Ionized Calcium
The Ionized Calcium Test measures the level of free, unbound calcium in the blood, which is the form actively available for vital physiological processes. Unlike total calcium measurements, which include both bound and unbound calcium, ionized calcium specifically reflects the calcium that directly influences nerve function, muscle contraction, and bone health. This test is crucial for evaluating calcium balance and diagnosing conditions such as parathyroid disorders, kidney disease, or vitamin D deficiency. It involves collecting and analyzing a blood sample to obtain an accurate measurement of active calcium in the bloodstream, guiding effective diagnosis and treatment.
Regular testing is typically recommended as needed based on symptoms or conditions affecting calcium levels.
