The revised Lund-Malmö GFR estimating equation outperforms MDRD and CKD-EPI across GFR, age and BMI intervals in a large Swedish population Abstract Background: The performance of creatinine-based glo-merular filtration rate (GFR) estimating equations may vary in subgroups defined by GFR, age and body mass index (BMI).

May 27, 2013 The Modification of Diet in Renal Disease (MDRD) Study equation has been proposed since 1999 to replace prior equations to better estimate 

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. [23] This led the group to prepare recommendations to standardize and improve creatinine measurement.[24] The CKD-EPI equation is a more accurate equation for estimating GFR. The Modification of Diet in Renal Disease (MDRD) equation is known to underestimate GFR in many individuals. What this means. For patients with eGFR < 60 mL/min/1.73 m², the change from MDRD to CKD-EPI will result in an average increase of eGFR of 1.3 mL/min/1.73 m². The MDRD study aimed to investigate the effect of protein restriction and blood pressure control on the progression of disease in patients with chronic renal diseases. The study hypothesized that a reduction in dietary protein and phosphorous intake and the maintenance of blood pressure below recommended levels would delay the progression of CKD-EPI Creatinine Equation (2009) CKD-EPI Creatinine-Cystatin Equation (2012) CKD-EPI Cystatin C Equation (2012) MDRD Study Equation; Learn more about CKD-EPI Collaboration and estimating GFR at www.ckdepi.org.

Epub 2007 Mar 1. A more accurate accurate method to estimate glomerular filtration rate from serum creatinine: a new prediction equation.

The MDRD formula for estimation of GFR is recommended for routine use and is reported with all requests for serum creatinine. See below for further information. Estimate of GFR by the Cockcroft and Gault equation (which requires patient age, sex, weight or height, and serum creatinine).

The Modification of Diet in Renal Disease (MDRD) Study equation and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation are the most widely used IDMS traceable equations for estimating GFR in patients age 18 and over.

The MDRD Equation: The MDRD equation was originally developed as a measure of eGFR before creatinine assays were standardized. That assay standardization resulted in a 10-25% decrease in many creatinine assays, and a “standardized” MDRD equation was … MDRD equations perform significantly better than the commonly used C&G formula.
