Ver el código de «Ionized calcium»

==Background==
*Physiologically active form of calcium (not bound to albumin)
*More accurate than total calcium, especially in critically ill or hypoalbuminemic patients

==Normal Values==
*Normal: 1.10-1.30 mmol/L (4.4-5.2 mg/dL)

==Interpretation==
*Preferred test in the ED for patients with low albumin, acid-base disturbances, or critical illness
*Acidosis increases ionized calcium (H+ displaces Ca from albumin); alkalosis decreases it
*Massive transfusion with citrated blood products can cause acute ionized hypocalcemia
*Symptomatic hypocalcemia (tetany, seizures, hemodynamic instability): treat with IV calcium gluconate or calcium chloride
