Measurement of glomerular filtration rate by inulin clearance without urine collection.
A continuous infusion method for measuring inulin clearance (and hence glomerular filtration rate) which does not require urine collection has been re-evaluated and found to give satisfactory results. In two non-oedematous and anephric patients the plasma level of inulin became virtually constant four hours after a single intravenous dose, and hence this is the minimum time required for the inf...
متن کاملThe accuracy of creatinine clearance with and without urine collection as a measure of glomerular filtration rate.
Conventional creatinine clearances involving urine collections over 2, 4 and 24 hours and creatinine clearance predicted from plasma creatinine concentrations without urine collection were compared to glomerular filtration rate (GFR) estimated by 99mTc DTPA clearance in 171 patients with a wide range of GFR. All creatinine clearance methods involving urine collection had standard errors of the ...

متن کاملMeasurement of Glomerular Filtration Rate by Rapid Intravenous Injection of a Newly Developed Inulin Fraction
OBJECTIVE Since the conventional drip-infusion method for measuring inulin clearance (Cin) has problems related to its accuracy and performance, we explored a more accurate and concise method by rapid intravenous injection of a newly developed inulin fraction (Inulead(®)), in which spot urine sampling was omitted and the administration period of inulin was shortened from 120 to 5 minutes. PAT...
متن کاملSerial determination of glomerular filtration rate in conscious mice using FITC-inulin clearance.
Two nonradioactive methods for determining glomerular filtration rate (GFR) in conscious mice using FITC-labeled inulin (FITC-inulin) were evaluated. The first method measured GFR using clearance kinetics of plasma FITC-inulin after a single bolus injection. Based on a two-compartment model, estimated GFR was 236.69 +/- 16.55 and 140.20 +/- 22.27 microl/min in male and female C57BL/6J mice, res...
