5 May 2009 To develop a new estimating equation for GFR: the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Design: Cross-
CKD-EPI creatinine-cystatin C equation CKD-EPI Creatinine-Cystatin C was developed in 2012 to estimate GFR from serum creatinine, cystatin C, age, sex, and race. The equation had similar bias to the creatinine or cystatin C equations but was more precise and therefore had greater overall accuracy.
2 Hintergrund "CKD-EPI" steht für "Chronic Kidney Disease Epidemiology Collaboration". Die Formel wurde mithilfe eines großen Probandenkollektivs (> 8.000 Teilnehmer) entwickelt und mit fast 4.000 weiteren Teilnehmern validiert. with the CKD-EPI equation. Apart from this, the results for men and women are essentially analogous for each age group. However, although eGFRs are generally lower in both men and women aged over 70 with the CKD-EPI formula, the increase in CKD stages 3 e 5 in this age group is due to an increase in the number of men rather than women.
The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation (2009) to estimate GFR. NKF and the American Society of Nephrology have convened a Task Force to focus on the use of race to estimate GFR. Read more about the task force here. 2016-03-29 · With the CKD-EPI equation, the mean ratio was high in children but decreased with increasing age; it was closer to 1 than the mean ratio from the Schwartz equation in participants older than 65 y (0.93 [95% CI 0.89; 0.97]) . Doseringen av läkemedel som främst utsöndras via njurarna (renal elimination) bör vid nedsatt njurfunktion anpassas så att läkemedelskoncentrationen inte blir för hög och allvarliga biverkningar drabbar patienten. Detta är särskilt viktigt hos äldre, eftersom njurfunktionen påtagligt minskar med stigande ålder.
Results consistently below 60mL/min/1.73m2 indicate chronic kidney disease. eGFR can also be calculated by using the eGFR calculator below. *This calculator uses the CKD-EPI formula. Some pathology results may use an alternate formula, which will result in slightly different result. Please note the calculator is not valid for people under the age
Im Grenzbereich von gesunder Funktion und beginnender Niereninsuffizienz ist sie genauer als die MDRD-Formel. Results consistently below 60mL/min/1.73m2 indicate chronic kidney disease. eGFR can also be calculated by using the eGFR calculator below.

The equation had similar bias to the creatinine or cystatin C equations but was more precise and therefore had greater overall accuracy. eGFR (CKD-EPI) = 141 x min (Scr/k, 1)alpha x max (Scr/k,1)-1.209 x 0.993age x 1.018 (if patient is female) x 1.159 (if patient is black) -where age is in years -k is 0.7 for females and 0.9 for males -alpha is -0.329 for females and -0.411 for males eGFR in ml/min /1.73 m2: Please enter data Age years Sex Male Female Race Non Black Black Creatinine mg/dL μmol/L Cystatin mg/L Calculate Results MDRD Study(ml/min/1.73 m2) CKD-EPIcr(ml/min/1.73 m2) CKD-EPIcys(ml/min/1.73 m2) CKD-EPIcr-cys C(ml/min/1.73 m2) … CKD-EPI Cystatin Equation.
It was published in 2012.13. The CKD-EPI cystatin equation is: eGFR = 133 x min(Scys/0.8, 1)-0.499 x max (Scys/0.8, 1)-1.328 x 0.996age x 0.932 [if female] where:
Glomerular filtration rate (GFR) is the best overall index of kidney function. 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.

Het voordeel van de CKD-EPI formule is dat die een meer accurate schatting geeft van de eGFR dan de 4 parameter-MDRD formule (4) en minder misclassificatie meebrengt (4).
