Background The plasma level of cystatin C is a better marker than plasma creatinine for successful aging. It has been assumed that the advantage of cystatin C is not only due to it being a better marker for glomerular filtration rate (GFR) than creatinine, but also because an inflammatory state of a patient induces a raised cystatin C level.

The heart pumps about 5 L blood per min under resting conditions. Approximately 20 percent or one liter enters the kidneys to be filtered. The evaluation of renal function is therefore of critical importance in diabetic subjects. Glomerular filtration rate (GFR) is the best measure of overall kidney function in health and disease . Serum creatinine concentration is widely used as an indirect marker of GFR, but it is influenced by muscle mass and diet . Because glomerular filtration is a nonselective process, the concentrations of these substances are the same in both blood plasma and glomerular filtrate. Glomerular Filtration Rate.

Glomerular filtration is a passive process as cellular energy is not used at the filtration membrane to produce filtrate. Glomerular filtration ratedeclines progressively following the onset of complete ureteral obstruction. The maintenance of glomerular filtration following ureteral obstruction is a result of (1) the reabsorption of salt and water along the nephron, (2) the ability of the renal tract to dilate, and (3) alterations in renal hemodynamics. As renal function declines, however, the serum/plasma concentration of any analyte produced in the body at a relatively constant rate and removed exclusively by glomerular filtration will increase as a reciprocal function: GFR = (U x × V)/P x, where (U x × V) is the urine excretion rate of analyte x and P x is the plasma concentration of x (i.e., GFR ∝ 1/P x). Glomerular filtration rate (GFR) is directly related to the pressures that determine net filtration pressure; any change in net filtration pressure will affect glomerular filtration rate.

Meaning of Glomerular Filtration Rate (GFR): Amount of filtrate formed by both kidneys together in unit time is called GFR. It is about 20% of the renal plasma flow. Normal value is […] 2018-12-14 · The glomerular filtration surface is comprised of endothelium, basement membrane and the feet of podocytes.

Glomerular filtration rate describes the flow rate of filtered fluid through the kidney. Creatinine clearance rate (CCr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Glomerular Filtration Rate Glomerular filtration rate (GFR) is the measure that describes the total amount of filtrate formed by all the renal corpuscles in both kidneys per minute. The glomerular filtration rate is directly proportional to the pressure gradient in the glomerulus, so changes in pressure will change GFR. The glomerular filtration rate (GFR) is closely correlated with unchanged drug elimination through the kidney and is useful in determining dosage adjustments. The Cockcroft and Gault formula is the most commonly used method of calculating the creatinine clerarance (Clcr), which has traditionally been used to approximate the GFR.
