Important: Inputs must be complete to perform calculation.

 
 
FEMg  
 
Decimal precision  

 
 

 
Notes
  • The fractional excretion of magnesium (FEMg) can be calculated by entering the values from simultaneously obtained urine and blood samples.
  • Please refer to UpToDate topic review of hypomagnesemia for a discussion of the interpretation of the fractional excretion of magnesium.
  • Cr: creatinine.
  • * This calculator uses SI units (Système international d'unités) as the default for inputs. Do not use this calculator if you are using conventional units (also known as US units and gravimetric units); please refer instead to the conventional units version of this calculator.

 
Equations used
 
FEMg = 100 * (Urine_Mg * Plasma_Cr) / (0.7 * Plasma_Mg * Urine_Cr)

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
