Estimates glomerular filtration rate based on creatinine and patient characteristics.
Only for chronic kidney disease (CKD), not accurate for acute renal failure. Please also note that a recent study indicates the MDRD may underestimate the actual GFR in healthy patients by up to 29%.
GFR = 175 x SerumCr-1.154 * age-0.203 * 1.212 (if patient is black) * 0.742 (if female)
