Glomerular Filtration Rate Estimation

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)

P_Cr x 72
x 0.85 (for women)

² Modification of Diet in Renal Disease (MDRD) : GFR = 170 x P_Cr^{- 0.999} x Age^{- 0.176} x BUN^{- 0.170} x Albumin^0.318 x 0.762 (for women) x 1.180 (for blacks)
