Rule et al developed an equation for predicting glomerular filtration rate (GFR) from serum creatinine. The authors are from the Mayo Clinic.
(1) serum creatinine in mg/dL
(2) age of the patient in years
(3) gender of the patient
serum creatinine for formula in mg/dL =
= MAX(0.8, measured serum creatinine)
Gender of the Patient
= (5.249 / (serum creatinine)) - (2.114 / ((serum creatinine)^2)) - (0.00686 * (age in years)) - (0.205 * (gender points)) + 1.911
estimated GFR in mL per min per 1.73 square meter =
