Creatinine-Based Estimated Glomerular Filtration Rate (eGFR) Test code:375 Clinical use Detect chronic kidney disease (CKD) in adults Monitor CKD therapy and/or progression in adults Clinical background About 37 million people in the United States are currently affected by CKD, and ...
Your kidneys filter creatinine from the blood into the urine and reabsorb almost none of it. The serum creatinine is then used to estimate the GFR (eGFR) based on a formula. Why Creatinine Tests Are Done Doctors use serum creatinine and eGFR to check how well your kidneys work. As kidney...
Revised equations for estimating glomerular filtration rate based on the Lund-Malm Study cohort. Objective. To increase the accuracy of estimated GFR (eGFR) from creatinine overall and at measured GFR 90 mL/min per 1.73 m2 by revising the Lund-Malm (LM... J Bj?Rk,A Grubb,G Sterner,......
However, eGFRcys is not more accurate than creatinine-based estimating equations (eGFRcr); rather, it is the combination of the two markers (eGFRcr-cys) that results in the most accurate eGFR. The CKD-EPI 2012 creatinine-cystatin and cystatin C equations were developed using cystatin C ...
Serum creatinine-based eGFR and serum cystatin C-based eGFR are the most popular methods for measuring renal function. Thyroid hormone is known to affect serum creatinine-based eGFR and serum cystatin C-based eGFR; however, the clinical significance of thyroid dysfunctional patients of renal function...
eGFR that shows kidney performance is calculated by the CKD-EPI creatinine equation, based on the serum creatinine concentration in blood (a breakdown product resulting from the activity of muscles), race, sex and age [4]. In developing countries such as India and Pakistan, which together are ...

Results: In the development data set, the new Japanese coefficient was 0.808 (95% confidence interval, 0.728 to 0.829) for the IDMS-MDRD Study equation (equation 3), and the 3-variable Japanese equation (equation 4) was eGFR (mL/min/1.73 m2) = 194 x Serum creatinine(-1.094) x Age(-...
13 Among 36 973 adults aged 20 to 79 years, we excluded those (1) with missing CVH scores (n = 6744), (2) without information on urine albumin and creatinine levels or estimated glomerular filtration rate (eGFR) (n = 305), (3) with a UACR of 30 mg/g or greater (n...
Among the three groups, patients in the non-albumin-predominant group tended to have lower levels of eGFR, serum albumin, hemoglobin, total cholesterol, triglyceride, and urine creatinine levels (Table 1). Clinical characteristics based on the uAPR quartile Only patients in the lowest quartile of...
