Mathematical description of equations for estimating glomerular filtration
| MDRD4 | Estimated GFR=186×(creatinine)−1.154×(age)−0.203×(0.742 if female)×(1.210 if black) |
| Cockcroft–Gault | Estimated creatinine clearance=((140−age)×weight/72×(creatinine))×(0.85 if female) |
GFR, glomerular filtration rate; MDRD, modified diet in renal disease.
