The CKD-EPI creatinine equation is based on the same four variables as the MDRD Study equation, but uses a 2-slope spline to model the relationship between estimated GFR and serum creatinine, and a different relationship for age, sex and race. The equation was reported to perform better and with less bias than the MDRD Study equation, especially in

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. -Report eGFRcreat in adults using the 2009 CKD-EPI creatinine equation. An alternative creatinine-based . GFR estimating equation is acceptable if it has been shown to improve accuracy of GFR estimates compared to the 2009 CKD-EPI creatinine equation. When reporting serum creatinine: The CKD-EPI Equation The CKD-EPI equation uses a 2-slope "spline" to model the relationship between GFR and serum creatinine, age, sex, and race. The equation is given in the following table for creatinine in mg/dL (see Appendix for creatinine in µmol/L).

From a serum creatinine measurement, it generates a GFR result normalized to a standard body surface area (1.73 m[2]) using sex, age, and race. Unlike the Cockcroft-Gault equation, height and weight, which are often not available in the laboratory information system, are not RESULTS: Although the bias of the CKD-EPI creatinine-cystatin C equation was greater than with the other equations (median difference, 5.7 mL/minute/1.73 m(2) versus a range from 0.4-2.5 mL/minute/1.73 m(2); P<0.001 for all), the precision was improved with the CKD-EPI creatinine-cystatin C equation (interquartile range for the difference, 19.5 mL/minute/1.73 m(2) versus a range from 23.0 … With the use of internationally standardized creatinine measurements, the equation significantly overestimates the GFR (10-40%). Because it includes weight in the equation, the output of the CG equation is in ml/min (compare to MDRD or CKD-EPI, with output units of ml/min/1.73m2). When we compared the concordance of CKD stages classified by various cystatin C equations versus CKD-EPI creatinine 2009 equation (Table 4(a)), the concordance was the highest with the average of creatinine 2009 and cystatin C 2012 (78.1%), followed by creatinine-cystatin C 2012—age, sex, and race (77.3%), and was the lowest with the spline Log cystatin C—age, sex, and weight (59.3%). The CKD-EPI creatinine and the MDRD Study equations perform better than the alternative creatinine-based estimating equations in solid-organ transplant recipients.

The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was introduced to estimate glomerular filtration rate (GFR) in chronic kidney disease (CKD) patients based on serum creatinine. The CKD-EPI equation, expressed as a single equation, is: GFR = 141 * min(Scr/κ,1) α * max(Scr/κ, 1) -1.209 * 0.993 Age * 1.018 [if female] * 1.159 [if black] Scr is serum creatinine (mg/dL), κ is 0.7 for females and 0.9 for males, α is -0.329 for females and -0.411 for males, min indicates the minimum of Scr/κ or 1, and max indicates the maximum of Scr/κ or 1. The Cockcroft-Gault (CG) formula is provided on this website for research purposes only. It should not be used for drug dosing or to estimate GFR. The best way to determine drug dosing is with the CKD-EPI Creatinine Equation (2009) or the MDRD Study.

Because it includes weight in the equation, the output of the CG equation is in ml/min (compare to MDRD or CKD-EPI, with output units of ml/min/1.73m2). Noninvasively estimates the measured GFR to determine degree or presence of decreased kidney function.

GFR equations. To evaluate the performance of the CKD-EPI creatinine-cystatin C equation in subjects with cirrhosis, we compared it to GFR measured by

mg/dL μmol/L. Creatinine can also be assayed in urine, for example so as to estimate creatinine clearance (requires blood and 24h urine collection within +/-24h of each other).This is now rarely required as largely replaced by calculation of estimated glomerular filtration rate (eGFR), or by use of the Cockroft-Gault equation as appropriate.

When we compared the concordance of CKD stages classified by various cystatin C equations versus CKD-EPI creatinine 2009 equation (Table 4(a)), the concordance was the highest with the average of creatinine 2009 and cystatin C 2012 (78.1%), followed by creatinine-cystatin C 2012—age, sex, and race (77.3%), and was the lowest with the spline Log cystatin C—age, sex, and weight (59.3%). In the receiver operating characteristic (ROC) curve analysis with a cut-off of GFR 45 mL/min/1.73 m(2), a higher diagnostic accuracy was achieved with the equation that uses both serum creatinine and cystatin C (CKD-EPI creatinine and cystatin formula) than the MDRD formula (P < 0.013) or CKD-EPI creatinine formula (P < 0.01), but it was not higher than that achieved for the simple cystatin C Serum creatinine is ordered more than 281 million times annually in the United States (based on the 191,354,358 creatinine tests reported in 1996 and assuming annual growth rate in testing of 3%),1 and recent reports show that more than 70% of laboratories now report estimated glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease (MDRD) Study equation.2 Recently, the The Cockcroft-Gault equation was published in 1976 and was widely adopted for estimation of creatinine clearance from serum creatinine levels (1). The equation was developed using two steps: First, urinary creatinine excretion per body weight (UV/kg) was estimated from age in hospitalized patients; creatinine clearance was then calculated by multiplying by weight and dividing by serum The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation was developed in an effort to create a more precise formula to estimate glomerular filtrate rate (GFR) from serum creatinine and other readily available clinical parameters, especially at when actual GFR is >60 mL/min per 1.73m 2. 6 GFR Equations - Estimating GFR in the Elderly (With SI Units) 4 variable MDRD Equation, CKD-EPI Equation, CKD-EPI Cystatin C Equation (2012) and CKD-EPI Cystatin C-Creatinine Equation (2012), BIS 1 and BIS 2 Equations (with SI Units) using standardized serum creatinine, age, race, gender and cystatin C 2020-10-01 · Background: The directly measured glomerular filtrate rate (mGFR) is the gold standard for kidney function, but it is invasive and costly. The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations have been widely used to estimate GFR, however, the comparative accuracy of estimated GFR (eGFR) using creatinine and cystatin C in CKD-EPI equations remains unclear.

3. Wieneke Marleen M., Grootendorst D. et al : Performance of the Cockcroft-Gault, MDRD, and New CKD-EPI Formulas in Relation to GFR, Age, and Body Size. The CKD-EPI equation was developed in 2009 using data from 8254 people with and without CKD in 10 studies and validated in 3896 people in 16 separate populations. 3 Creatinine assays for all studies were standardized to higher-order reference materials 15 When used with standardized creatinine assays, the CKD-EPI equation generally yields higher levels for eGFR than the MDRD Study equation par l’équation CKD-EPI Doser la créatininémie par méthode enzymatique Pour diagnostiquer une insuffisance rénale chronique chez l’adulte, la fonction rénale doit être évaluée en pratique, à partir de la créatininémie, par l’estimation du débit de filtration glomérulaire (DFG) et non plus RESULTS: Although the bias of the CKD-EPI creatinine-cystatin C equation was greater than with the other equations (median difference, 5.7 mL/minute/1.73 m(2) versus a range from 0.4-2.5 mL/minute/1.73 m(2); P<0.001 for all), the precision was improved with the CKD-EPI creatinine-cystatin C equation (interquartile range for the difference, 19.5 mL/minute/1.73 m(2) versus a range from 23.0-23.6 2017-08-11 · LMR equation than the CKD-EPI creatinine equation. The similar precision of the CAPA equation to the CKD-EPI cystatin C equation is consistent with the smaller inﬂuence of race on Figure 1. Performance of GFR estimating equations in Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) validation databases. The CKD-EPI creatinine-based estimation equation for glomerular filtration rate (GFR) cannot be used in children, overestimates GFR in young adults, and its combination with the KDIGO recommended pediatric CKiD (Schwartz bedside) equation causes implausible increases in estimated GFR when switching from pediatric to adult care.
