Calculate kidney function by Cockcroft-Gault formula
Glomerular filtration rate (GFR) is the best overall index of kidney function. Normal GFR varies according to age, sex, and body size, and declines with age.
Software use Cockcroft-Gault (for GFR) and the DuBois formula (for BSA) to show value in mL/min/1.73m2. It be recommend by NKF's KDOQI clinical practice guidelines to estimate GFR.
