MDRD estimates the glomerular filtration rate (GFR) based on serum creatinine, age, and race of the patient. The calculation is based on a standard body surface area (BSA) of 1.73 m2. Strong deviations of the anthropometric data (height, weight) from the norm can distort the result. A correction for the actual BSA can lead to a better estimate of the GFR.
