Determining the Glomerular Filtration Rate—An Overview

Web17 nov. 2024 · The rate of clearance by secretion depends on renal blood flow Molecules which are too large to be filtered in the glomerulus may still be cleared renally by these mechanisms Protein-bound drugs are not cleared this way; only the unbound fraction is available for active secretion. Notable substrates for active transport include: WebClearance, the parameter which relates rate of elimination to drug concentration, is important because it defines the rate of administration required to maintain a plateau drug concentration. Together with the extent of distribution outside of plasma, clearance also determines the speed at which a drug is eliminated from the body.

WebAs given above, the normal GFR is 125 ml/min. If this number is compared to the renal blood flow, RBF = 1200 ml/min, it becomes obvious that only 11% of the blood is filtered: (125/1200) * (100) = 11%. For individu al patients with some renal dysfunction, the GFR is often determined from the creatinine clearance. WebClearance studies are widely used to assess glomerular filtration rate and renal blood flow and to study the excretion of various substances by the kidney. The renal clearance of a substance represents the virtual or theoretical volume of plasma which is completely cleared of this substance in a given unit of time.
