<p><b>Página nueva</b></p><div>==Background==<br />
*Physiologically active form of calcium (not bound to albumin)<br />
*More accurate than total calcium, especially in critically ill or hypoalbuminemic patients<br />
<br />
==Normal Values==<br />
*Normal: 1.10-1.30 mmol/L (4.4-5.2 mg/dL)<br />
<br />
==Interpretation==<br />
*Preferred test in the ED for patients with low albumin, acid-base disturbances, or critical illness<br />
*Acidosis increases ionized calcium (H+ displaces Ca from albumin); alkalosis decreases it<br />
*Massive transfusion with citrated blood products can cause acute ionized hypocalcemia<br />
*Symptomatic hypocalcemia (tetany, seizures, hemodynamic instability): treat with IV calcium gluconate or calcium chloride<br />
