eGFR (estimated glomerular filtration rate) = mL/min/1.73 m 2. S Cr (serum creatinine) = mg/dL. S cys (standardized serum cystatin C) = mg/l. κ = 0.7 (females) or 0.9 (males) α = -0.248 (females) or -0.207 (males) min (S Cr /κ or 1) = indicates the minimum of S Cr /κ or 1. 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.

Expressing the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) cystatin C equations for estimating GFR with standardized serum cystatin C values. Am J Kidney Dis. 2011;58(4):682-684. Introduction: We previously reported a modification to the Modification of Diet in Renal Disease (MDRD) Study equation for use in Japan. Recently, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) developed a new equation that is more accurate and yields a lower CKD prevalence estimate in the United States than the MDRD Study equation. CKD-EPI Cystatin C was developed in 2012 to estimate GFR from serum cystatin C, age, and sex. The equation has similar accuracy to the CKD-EPI Creatinine 2009 Equation.

Kidneys filter the blood of wastes and toxins, allowing them to be expelled through urine. Disease Epidemiology (CKD-EPI) Collaboration equation [4], both developed during the 21st century, has been thoroughly validated and CKD-EPI is the primary choice of the 2013 international recommendation of the KDIGO (for “Kidney Disease: Improving Global Outcomes”) [1]. However, none of these two equations is optimal for all Noninvasively estimates the measured GFR to determine degree or presence of decreased kidney function.

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. Even though FAS equations were validated for Caucasians only, the study of Bukabau et al. , with 494 participants from Democratic Republic of Congo and Ivory Coast, showed that both FAS and CKD-EPI equations without race-ethnicity adjustment had the best performance in those with normal GFR, whereas FAS equation had a smaller bias and higher accuracy in the individuals with GFR below <60 mL Se hela listan på academic.oup.com 2015-12-01 · Of these equations, the CKD-EPI equation that combines creatinine and cystatin C (CKD-EPI-Cr-CysC) showed a bias of 0.12 ml/min/1.73 m(2) as compared to measured GFR. CONCLUSIONS: The CKD-EPI equation that combines serum creatinine and cystatin C measurements shows the best performance for accurate estimation of GFR in cirrhosis, especially at advanced stages. equations (around 41.2%), although percentages of patients with stages 2, 4 and 5 were increased in women 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 The rate therefore measured is the quantity of the substance in the urine that originated from a calculable volume of blood.

Recently, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) developed a new equation that is more accurate and yields a lower CKD prevalence estimate in the United States than the MDRD Study equation. Estimated glomerular filtration rate (eGFR): eGFR is calculated using the 2009 chronic kidney disease (CKD) epidemiology collaboration (CKD-EPI) equation: 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 Glomerular filtration rate-estimating equations for patients with advanced chronic kidney disease.
