Because a significant portion of calcium is bound to albumin, any alteration in the level of albumin will affect the measured level of calcium. A corrected calcium level based on the albumin level is: Corrected calcium (mg/dL) = measured total Ca (mg/dL) + 0.8 * (4.0 - serum albumin [g/dL]). Since calcium is also bound to small anions, it may be more useful to correct total calcium for b… WebECG changes in hypokalemia The following ECG changes occur in chronological order as potassium levels decrease.
