| ERPF | Effective Renal Plasma Flow |
| RPF | Renal Plasma Flow |
| RPF | renal plasma flow rate |
| CL | 1/clearance |
| renal plasma flow | <physiology> The amount of plasma that perfuses the kidneys per unit time, approximately 10% greater than effective renal plasma flow. It should be differentiated from the renal blood flow which refers to the total volume of blood flowing through the renal vasculature, while the renal plasma flow refers to the rate of plasma flow. (12 Dec 1998) |
|---|---|
| effective renal plasma flow | <physiology> The amount of plasma flowing to the parts of the kidney that have a function in the production of constituents of urine; the clearance of substances such as iodopyracet and p-aminohippuric acid, assuming that the extraction ratio in the peritubular capillaries is 100%. It is the amount of plasma perfusing the kidney tubules per unit time, generally measured by p-aminohippurate clearance. It should be differentiated from renal plasma flow which is approximately 10% greater than the effective renal plasma flow. (07 Mar 2000) |
| amylase-creatinine clearance ratio | A test for the diagnosis of acute pancreatitis; it is determined by measuring amylase and creatinine in serum and urine in apparently healthy individuals the renal clearance of amylase is less than 5% that of creatinine; in acute pancreatitis the ratio is said to be greater than 0.05 or 5%. (05 Mar 2000) |
| ANP clearance receptors | Cell surface proteins that bind atrial natriuretic peptide and ANP fragments without initiating biological action. (05 Mar 2000) |
| p-aminohippurate clearance | A good measure of renal plasma flow, which it slightly underestimates; when a low plasma concentration of p-aminohippurate (PAH) is maintained by intravenous infusion, the kidney extracts and excretes almost all of the PAH from the plasma before it reaches the renal vein. (05 Mar 2000) |
| maximum urea clearance | The urea clearance when the urine flow exceeds 2 ml/min; normal value is about 75 ml blood/min per 1.73 m2 body surface area. (05 Mar 2000) |
| metabolic clearance rate | Volume of biological fluid completely cleared of drug metabolites as measured in unit time. Elimination occurs as a result of metabolic processes in the kidney, liver, saliva, sweat, intestine, heart, brain, or other site. (12 Dec 1998) |
| clearance | 1. The process of clearing. 2. <physiology> The rate at which a substance is removed from the blood. (18 Nov 1997) |
| mucociliary clearance | Rate of ciliary and secretory activity of the respiratory submucosal glands. It is a non-specific host defense mechanism, measurable in vivo by mucus transfer, ciliary beat frequency, and clearance of radioactive tracers. (12 Dec 1998) |
| creatinine clearance | Measurement of the clearance of endogenous creatinine, used for evaluating the glomerular filtration rate (GFR). (05 Mar 2000) |
| creatinine clearance test | <investigation, nephrology> A test of the amount of creatinine in blood or in blood and urine shows if the kidneys are working right or if one or both are diseased. (09 Oct 1997) |
| standard urea clearance | The value obtained when the square root of the urine flow (when below 2 ml/min) is multiplied by the urine urea concentration and divided by the whole blood urea concentration; represents an old empirical adjustment for the effect of low urine flow on urea excretion; sometimes corrected for body size by dividing by some function of body weight or surface area. Later, plasma concentration was substituted for blood concentration in the calculation. The normal value is about 54 ml/min per 1.73 m2 in an adult person. Synonym: Van Slyke's formula. (05 Mar 2000) |
| steroid metabolic clearance rate | A measure of the rate of metabolism of a given steroid within the body, usually expressed as liters of body fluid that contain the amount of steroid metabolised per day. (05 Mar 2000) |
| interocclusal clearance | The space between the occluding surfaces of the maxillary and mandibular teeth when the mandible is in physiologic resting position. Synonym: interocclusal clearance, interocclusal distance, interocclusal gap, interocclusal rest space. (05 Mar 2000) |
| inulin clearance | An accurate measure of the rate of filtration through the renal glomeruli, because inulin filters freely with water and is neither excreted nor reabsorbed through tubule walls. Inulin is not a normal constituent of plasma and must be infused continously to maintain a steady plasma concentration and a steady rate of urinary excretion during the measurement. Inulin clearance in a normal adult person is about 120 ml/min (range 100-150) per 1.73 m2 body surface area. (05 Mar 2000) |
