MDRD eGFR. Calculate eGFR using the MDRD formula. Questions. 1.Gender? 2.Race? 3.Age? 4.Creatinine? About. This formula may not be accurate when used in children, elderly patients, specific ethnic groups, pregnant women, those with unusual muscle mass, body habitus, and weight (eg, morbid obesity, amputees) and patients with a normal GFR.

Normal GFR varies according to age, sex, and body size, and declines with age. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. The MDRD equation performed better in the GFR interval 30-89 mL/min/1.73 m(2), while accuracy was limited for both equations at GFR < 30 mL/min/1.73 m(2) (P-30 < 75% in both females and males). The CKD-EPI/MDRD equations caused a +22%/ +14% bias in the 18-39 year interval and the MDRD equation a + 18% bias >= 80 years. The MDRD formula for estimation of GFR is recommended for routine use and is reported with all requests for serum creatinine.

MDRD STUDY EQUATION: mdrd (Age, Race, Gender, Plasma creatinine) Chronic kidney disease (GFR less than 60 or kidney damage for at least three months) *All ethnic groups other than African American Shortcut: Type underlined letters to toggle between variables The MDRD equation is used in estimating GFR in stable chronic kidney disease and cannot be used in acute renal failure. Compared to other methods of estimating GFR, the one in question has been validated and shows better correlation than other equations such as the Cockcroft-Gault formula.

Moreover, the MDRD6 equation provides the best diagnostic performance, and should therefore be preferred in renal transplant recipients.

eGFR by MDRD Equation In adults, the most widely-used equations for estimating glomerular filtration rate (GFR) from serum creatinine are the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation 1 and the isotope dilution mass spectrometry (IDMS) traceable Modification of Diet in Renal Disease (MDRD) Study equation 2.

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. 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) Abbreviations / Units. eGFR (estimated glomerular filtration rate) = mL/min/1.73 m 2.

The GFR (glomerular filtration rate) Calculator estimates GFR values based on in Renal Disease (MDRD) Study equation or the CKD-EPI equation provides a

1. However, the MDRD four-variable formula is not as well-. validated as one might hope. Firstly, despite The MDRD equation yielded lower estimates of eGFR than the CKD-EPI equation, with small mean difference between the equations at low eGFR level but substantial at the level of only mildly decreased or near-normal to normal kidney function. Decrease of eGFR was associated with an increase in CKD and CVD risk factors.
