The MDRD Equation. The following is the IDMS-traceable MDRD Study equation (for creatinine methods calibrated to an IDMS reference method) GFR (mL/min/1.73 m 2) = 175 × (S cr)-1.154 × (Age)-0.203 × (0.742 if female) × (1.212 if African American) The MDRD1 equation provided the best predictive model (narrowest limits of agreement; r = 0.766, p < 0.001), and the highest performance in predicting a GFR less than 60 ml/min/1.73 m2 (area under curve: 0.901).

Noninvasively estimates the measured GFR to determine degree or presence of decreased kidney function. The MDRD equation performs equally to the newer CKD-EPI Equation in patients with GFR of < 60 ml/min/1.73m2. Performs superiorly to the Cockcroft-Gault Equation.

Using the 4-parameter MDRD equation, we compared the eGFR calculated from creatinine values obtained by various field methods between 2006 and 2011. Recent trends in performance and current state of creatinine assays MDRD equations perform significantly better than the commonly used C&G formula. Moreover, the MDRD6 equation provides the best diagnostic performance, and should therefore be preferred in renal transplant recipients. See also MDRD equation with 6 inputs ().Normal GFR in mL/min/1.73 m2 of body surface area. See .. Limitations: The MDRD Study included few patients with a GFR greater than 90 mL/min per 1.73 m2.

Use the CKD-epi equations in persons over The 2012 CKD-EPI equations with creatinine and/or cystatin C significantly overestimate GFR in stage 1 and 2 chronic kidney disease. The MDRD equation is CG formula. 2.

145 (4): 247 -- Annals of Internal Medicine: MDRD equation The 4-variable MDRD Study equation was developed in 1999 using data from 1,628 patients with CKD with GFR from approximately 5 to 90 milliliters per minute per 1.73 m 2 . It estimates GFR adjusted for body surface area and is more accurate than measured creatinine clearance from 24-hour urine collections or estimated by the The group further concluded that all current equations for estimating GFRs, including the MDRD equations and the Cockcroft–Gault equation, are less accurate in patients with normal and slightly increased serum creatinine.

This IDMS-traceable MDRD study equation calculator is for use when S cr is reported in mg/dL. This equation should not be used when eGFR values above 60 mL/min/1.73 m² are desired. GFR (mL/min/1.73 m²) = 175 × (S cr) -1.154 × (Age) -0.203 × (0.742 if female) × (1.212 if African American) (conventional units)
