The accurate assessment of glomerular filtration rate (GFR) is important in the follow-up of kidney transplant recipients in order to identify graft dysfunction. A number of formulas have been proposed to calculate GFR from endogenous plasma markers such as creatinine or cystatin C since measuring GFR using exogenous markers is troublesome.

Comparison of estimated GFR and measured GFR in prospective living kidney donors
International Urology and Nephrology, 2014The aim of this study was to examine the usefulness of three GFR-estimating equations (eGFR) compared with measured GFR (mGFR) in potential living kidney donors.We compared the performance of the MDRD, CKD-Epi and Cockcroft-Gault equations with mGFR measured using (51)Cr-EDTA in 508 consecutive potential living kidney donors. Each equation was assessed

You are asked to review a 67 year old man. He is 48 h following a hemicolectomy and complains of abdominal pain. He is drowsy but rousable, his heart rate is 97 beats per min, his blood pressure 97/60 mmHg. You note his empty catheter bag and discover he has been completely anuric for the last 9 h.

Contrast media as markers of GFR
European Radiology, 2001Determination of the glomerular filtration rate (GFR) is generally considered as the most important parameter of quantifying renal function. The GFR is determined as renal or plasma clearance of an ideal filtration marker which is freely filtered by the kidney, does not undergo metabolism, tubular secretion or absorption.

Assessing bias in GFR estimating equations: improper GFR stratification can yield misleading results
Pediatric NephrologyAssessing bias (estimated - measured) is key to evaluating glomerular filtration rate (GFR). Stratification by subgroups can indicate where equations perform differently. However, there is a fallacy in the assessment of two instruments (e.g., eGFR and mGFR) when stratifying on the level of only one of those instruments.

Glomerular Filtration Rate (GFR)
2009Glomerular membranes of the kidney filtrate about 130 ml of plasma/min or 190 L/day; about 1.8 L of this volume is excreted as urine, the remainder reabsorbed in the renal tubules; it can be calculated by the formula of Jelliffe (Ann Int Med 79:604–605, 1973); GFR = (98 − 0.8(age-20)) × body surface area/(serum creatinine × 1.73); the result is to be ...

The resting kidneys receive around 20 % of the normal cardiac output. About 90 % of this renal blood flow enters the nephrons (estimated 1 million/kidney) to be filtered at the glomerulus. Filtration is a voluminous event, 125 ml/min or 180 L daily. In a 70 kg male adult, the total body fluid is 42 L of which extracellular fluid (ECF) volume is a third
