Our free Corrected Magnesium Calculator helps medical professionals and individuals accurately assess magnesium levels by factoring in serum albumin. This tool is vital for correctly interpreting magnesium results, especially in patients with hypoalbuminemia, ensuring proper diagnosis and treatment of conditions like hypomagnesemia.
Formula:
The formula for corrected magnesium is:
Corrected Magnesium (mg/dL) = Measured Magnesium (mg/dL) + 0.005 × (40 - Serum Albumin (g/dL))
Where:
- Measured Magnesium: Your raw, reported magnesium level from a lab test.
- Serum Albumin: Your reported albumin concentration from a lab test.
- 0.005: A standard correction factor.
- 40: Represents a normal serum albumin level (4.0 g/dL).
Note: This formula assumes Measured Magnesium is in mg/dL and Serum Albumin is in g/dL.
