Test Code:
090-20-1201-01

Order Name:
Ionized Calcium

 
 
Clinical Information:
Ionized calcium, which accounts for 50% to 55% of total calcium, is the physiologically active form of calcium.

Low ionized calcium values are often seen in renal disease, critically ill patients, or patients receiving rapid transfusion of citrated whole blood or blood products.

Increased serum ionized calcium concentrations may be seen with primary hyperparathyroidism, ectopic parathyroid hormone-producing tumors, excess intake of vitamin D, or various malignancies.
 
Reference Value:
 Arterial Blood: 1.09-1.30 mmol/l
