Normal levels of ionized calcium are different in adults and children. In adults, a level of 4.64 to 5.28 milligrams per deciliter (mg/dL) is normal. In children, a normal ionized calcium level is 4.8 to 5.52 mg/dL. If you have low levels of ionized calcium in your blood, it can indicate:
Your doctor also may order a calcium test when you have:
osteomalacia or rickets, which is a softening of the bones (in many cases due to a vitamin D deficiency) If you have a high level of ionized calcium in your blood, it can indicate: milk-alkali syndrome, which is high levels of calcium in the body due to consuming too much milk, antacids, or calcium carbonate over time

Your provider may order this test if you have signs of bone, kidney, liver or parathyroid disease. The test may also be done to monitor progress and treatment of these diseases. Most of the time, blood tests measure your total calcium level. This looks at both ionized calcium and calcium attached to proteins.
Note: Providers are reminded to refer to the long descriptors of the CPT codes in their CPT book.CodeDescription82330Assay of calcium
It's often part of a basic metabolic panel (BMP) and a comprehensive metabolic panel (CMP), which are both routine screening tests. An ionized calcium test measures only the "free calcium" in your blood that isn't attached to proteins.
An ionized calcium test uses a small amount of your blood. A healthcare professional will get a blood sample by performing a venipuncture. They'll clean a section of skin on your arm or hand, insert a needle into your vein through your skin, and then draw a small amount of blood into a test tube.
Unspecified disorder of calcium metabolism E83. 50 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM E83. 50 became effective on October 1, 2021.
Adults: 4.8 to 5.6 mg/dL or 1.20 to 1.40 millimol/L.
Although "corrected" total calcium reflects ionized calcium more accurately than uncorrected total calcium in patients with abnormal serum protein concentration, none of the correction formulae are entirely reliable for all patients.
It is important for heart function. It also helps with muscle contraction, nerve signaling, and blood clotting. This article discusses the test used to measure the amount of ionized calcium in blood.
Conclusion: Ionized calcium may be better than corrected calcium for detecting hypercalcemia in patients with MM. Additional analyses are needed to better quantify the clinical impact of paraprotein calcium-binding.
Hypercalcemia is usually a result of overactive parathyroid glands. These four tiny glands are situated in the neck, near the thyroid gland. Other causes of hypercalcemia include cancer, certain other medical disorders, some medications, and taking too much of calcium and vitamin D supplements.
Low serum calcium concentrations are most often caused by disorders of PTH or vitamin D. Other causes of hypocalcemia include disorders that result in a decrease in serum ionized calcium concentration by binding of calcium within the vascular space or by its deposition in tissues, as can occur with hyperphosphatemia.

Abnormally high level of calcium in the blood; manifestations include fatigability, muscle weakness, depression, anorexia, nausea, and constipation. Higher than normal levels of calcium in the blood. Some types of cancer increase the risk of hypercalcemia.
