A blood calcium test is ordered to screen for, diagnose, and monitor a range of conditions relating to the bones, heart, nerves, kidneys, and teeth. con be ordered if a person has symptoms of a parathyroid disorder, malabsorption, or an overactive thyroid. A total calcium level is often measured as part of a routine health screening. It is included in the comprehensive metabolic panel (CMP) and the basic metabolic panel (BMP), groups of tests that are performed together to diagnose or monitor a variety of conditions. When an abnormal total calcium result is obtained,. To diagnose the underlying problem, additional tests are ordered to measure ionized calcium, urine calcium, phosphorous, magnesium, vitamin D, parathyroid hormone (PTH) and PTH-related peptide, PTH and vitamin D are responsible for maintaining calcium concentrations in the blood within a narrow range of values. If calcium is abnormal, measuring calcium and PTH together can help determine whether the parathyroid glands are functioning normally. Measuring urine calcium can help determine whether the kidneys are excreting the proper amount of calcium, and testing for vitamin D, phosphorus, and/or magnesium can help determine whether other deficiencies or excesses exist. Frequently, the balance among these different substances (and the changes in them) is just as important as the concentrations. Calcium can be used as a diagnostic test if a person has symptoms that suggest: Kidney stones Bone disease Neurologic disorders
