Description

Rule et al developed an equation for predicting glomerular filtration rate (GFR) from serum creatinine. The authors are from the Mayo Clinic.


 

Parameters:

(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

Points

male

0

female

1

 

X =

= (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 =

= EXP(X)
