Calcium Correction Calculator

Corrected calcium = serum calcium + 0.8 * (4 - serum albumin) Normal calcium levels are between 8.5 and 10.5 mg/dL, equivalent to 2.1-2.6 mmol/L. Total calcium in the body varies with the level of serum albumin which is the protein that binds calcium. Adjusted or corrected calcium relates to the ionized calcium rather than the total, the
