Glomerular filtration rate (GFR) is considered as the best way to assess global renal function (Gaspari et al., 1997; Stevens & Levey, 2009). Even if GFR estimations (based on creatinineor cystatin C-based equations) are most often used (see Table 1)(Cockcroft & Gault, 1976; Levey et al., 1999; Levey et al., 2006; Levey et al., 2009), measuring “true” GFR is still important in clinical practice...

The serious limitations of the estimating glomerular filtration rate (eGFR) appear related not to a shortcoming of the equation, but to the futility of trying to force agreement between two inherently different parameters: a blood marker of kidney function with a very stable concentration (creatinine) and a renal filtration parameter that fluctuates continually (glomerular filtration rate, GFR)...

While there is general agreement on the necessity to measure glomerular filtration rate (GFR) in many clinical situations, there is less agreement on the best method to achieve this purpose. As the gold standard method for GFR determination, urinary (or renal) clearance of inulin, fades into the background due to inconvenience and high cost, a diversity of filtration markers and protocols compe...

UNLABELLED Cystatin C, a cysteine protease inhibitor, has been recommended as a new marker of glomerular filtration rate (GFR). THE AIM OF STUDY We investigated significance of cystatin C in assessment of GFR and its influence on overall survival (OS) in patients with ovarian cancer (OC). MATERIAL AND METHODS We prospectively included consecutive patients with OC, who after surgery were quali...

OBJECTIVE Glomerular filtration rate (GFR) is used to assess the progression of renal disease. We performed linkage analysis to localize genes that influence GFR using estimated GFR data from the San Antonio Family Diabetes/Gallbladder Study. We also examined the effect of genotype by diabetes interaction (G x DM) on the detection of linkage to address whether genetic effects on GFR differ in d...

BACKGROUND Diabetic nephropathy (DN) is one of the most important complications of diabetes mellitus. Now-a-days, cystatin C (CysC) is introduced as a new marker for diagnosis of renal damages; however, use of this marker in clinical laboratories is still controversial. The present study was aimed to evaluate the diagnostic value of serum CysC for early detection or monitoring treatment of kidn...

A study was conducted to evaluate the usefulness of GFR to assess the renal involvement in hypertension. GFR was assessed using the conventional blood urea and serum creatinine values and the eGFR is calculated based on serum creatinine by using the MDRD formula and Cockcroft – Gault formula. The values obtained were compared with serum Cystatin C and Cystatin based eGFR. It was observed that e...

GFR is the best indicator of renal function in children and adolescents and is critical for diagnosing acute and chronic kidney impairment, intervening early to prevent end-stage renal failure, prescribing nephrotoxic drugs and drugs cleared by a failing kidney, and monitoring for side effects of medications. Renal inulin clearance was the gold standard for GFR but is compromised by lack of ava...
