MDRD CKD-EPI (Creatinine) CKD-EPI (Cystatin C) CKD-EPI (Creatinine-Cystatin C) Cockcroft-Gault

eGFR Glomerular Filtration Rate
(2006 Modified IMDS-MDRD)

International Unit: μmol/L, US Unit: mg/dL
Age
Years
Serum Creatinine
Glomerular Filtration Rate
ml/min/1.73 m2
This formula was improved by the original researchers in 2006, validated using more accurate isotope dilution mass spectrometry (IDMS-Traceable) measurements from 1628 clinical samples. This formula is only applicable for chronic kidney disease and not suitable for acute kidney failure. It should also be noted that a recent study indicates that for healthy individuals, the MDRD formula may underestimate the glomerular filtration rate by up to 29%.
eGFR=186×Scr-1.154×(age)-0.203×(0.742, female)
Where Scr is measured in mg/dL, age in years.
Note:
1. Scr is serum creatinine;
2. If the patient is African American, multiply the value by 1.212.
