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. By establishing sex-specific creatinine growth curves for children

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. They … Gary Theilman, Pharm.D.University of Mississippi School of Pharmacy 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. 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 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.

As expected, there is less bias (less underestimation) with the CKD-EPI equation in the highest GFR range (>90 mL/min/1.73 m 2). Previously, we found that the CKD-EPI equation based on the serum creatinine level exhibited a better performance than the MDRD equation in estimating the GFR in Chinese diabetics . In the present study, all six equations achieved high classification accuracy for stage 5 CKD (≥90.2%), no matter which serum creatinine or cystain C-based equation was used. CKD-EPI Equation The CKD-EPI equation was developed in 2009 using a diverse population estimate GFR from serum creatinine, age, sex and race.

This CKD-EPI equation calculator should be used when S cr is reported in mg/dL. This equation is recommended when eGFR values above 60 mL/min/1.73 m² are desired. The CKD-EPI Creatinine Equation (2009) 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.
