Fractional Excretion of Magnesium Formula
Equation for calculate fractional excretion of magnesium is,
FEMg = [(Mg(U) × Cr(S)) ÷ (Mg(S) × Cr(U))] × 100
Where,Mg = Magnesium (S, mg/dL)
Mg = Magnesium (U, mg/dL)
Cr = Creatinine (S, mg/dL)
Cr = Creatinine (U, mg/dL)
FEMg = Fractional Excretion of Magnesium (%)
