Q: In human body for measurement , each 1 g/dL decrease of albumin will raise the serum Calcium by what level?

Answer: Each 1 g/dL decrease of albumin raises the serum calcium (Ca) level by 0.8 mg/dL in human body. Remember the formula for calcium correction from internship days?

Corrected calcium (mg/dL) = measured total Ca (mg/dL) + 0.8 (4.0 - serum albumin [g/dL])
