Furthermore, differences in muscle mass need to be entered into the recommended equations for calculating the estimated glomerular filtration rate (eGFR) in athletes. Based on current knowledge about creatinine measurement and eGFR calculation, we suggest that athletes be monitored periodically by ...
Measurement of serum creatinine with calculation of the glomerular filtration rate is used to identify at-risk patients. The possible methods for measuring renal function using laboratory tests and the various equations for estimating glomerular filtration rate are reviewed, and questionnaires to replace ...
New Creatinine- and Cystatin C-Based Equations to Estimate GFR without Race. N Engl J Med. 2021 Nov 4;385(19):1737-1749. doi: 10.1056/NEJMoa2102953. Epub 2021 Sep 23. PMID: 34554658; PMCID: PMC8822996. TheeGFR using CKD-EPI (Creatinine-Cystatin C) Equation (2021)calculator is created...

Full size image Calculation of eGFRUsing the Chinese eGFR equation proposed by Ma Yingchun et al. [24], eGFR for each subject was calculated based on Scr, Cys-C, age, and sex: eGFR (mL/min/1.73m2) = 169 × Pcr-0.608× cysC-0.63× Age-0.157 ...
A mathematical calculation of the total amount of creatinine excreted in the urine over a period of time, usually 24 hours to test renal function. The calculation is: creatinine clearance (mL/minute) = urine creatinine concentration (mL/dL) × volume of urine (mL/24 hour) ÷ plasma creatinin...
modern estimates of glomerular filtration rate. TheMDRD equation, used to calculate "eGFR", was originally developed using a conventional serum creatinine assay and later was republished using IDMS-based values. The update to MDRD, called theCKD-EPI equation, exclusively relies on IDMS-based values...
I thought it might be helpful to others interested in this topic to expand further on the calculations I used in determining the uncertainty of eGFR. The abbreviated MDRD formula used involves only one measured result in the calculation of eGFR and hence the uncertainty of eGFR is dependent on...
(e.g., obstruction or extravasation of urine into the peritoneal cavity) may falsely elevate serum concentrations in the absence of parenchymal damage. Thus, a decrease in the eGFR inferred from an increase in the serum creatinine level may not distinguish among prerenal, intrinsic renal, and ...
The potential for unmeasured confounders between sACR levels and in-hospital mortality was also explored through the calculation of the E value. Results A total of 114 eligible patients were included in this sutdy. The multivariate logistic regression analysis indicated an independent association between...
