MedCalc: Glomerular Filtration Rate Estimation
* = optional

Patient's Age : years Sex :
Patient's Weight : * Race :
Serum Creatinine : mg/dL * Serum BUN : mg/dL
  * Serum Albumin : g/dL
Cockcroft-Gault GFR1 : mL/min
MDRD GFR2 : mL/min

1Cockcroft-Gault : GFR =
(140 - age) x weight (kg)
PCr x 72
x 0.85 (for women)
2 Modification of Diet in Renal Disease (MDRD) : GFR = 170 x PCr - 0.999 x Age - 0.176 x BUN - 0.170 x Albumin0.318 x 0.762 (for women) x 1.180 (for blacks)
