Nephrology: Adjusted anion gap = Measured anion gap + 2.5 x (4 - albumin)

Corrected calcium is a calculation used to adjust the total calcium levels based on the albumin concentration in the blood. The formula for corrected calcium is as follows:

Corrected Calcium (mg/dL) = Total Calcium (mg/dL) + 0.8 * (4 - Albumin (g/dL))

This formula helps compensate for the fact that calcium levels can be influenced by changes in albumin levels. If a patient has low albumin levels, the corrected calcium may provide a more accurate reflection of the actual calcium status.

It's important to note that while corrected calcium is a useful calculation, it is not a perfect measure, and clinical judgment should be exercised. If there are concerns about calcium status or if the patient has additional medical conditions, consultation with a healthcare professional is recommended for a comprehensive assessment.
