Corrected Calcium (CAC) Calculator

Posted by Dinesh on

Hypocalcemia is an electrolyte imbalance and is indicated by a low level of calcium in the blood. The normal adult value for calcium is 4.5-5.5 mEq/L. If your albumin is low, your calcium level should be corrected for this. A corrected calcium level will be higher if the albumin is low.

This calculator calculates the corrected calcium using calcium, albumin, normal albumin values.

Calcium Correction for Hypoalbuminemia

Formula:

Corrected calcium=sc+0.8×4-sa

Where,

cc is the corrected calcium
sc is the serum calcium
sa is the serum albumin
