database of 51Cr-ethylenediaminetetraacetic acid (51Cr-EDTA) renal clearance determinations using the two blood sample method, 598 patients, aged 1 week to 90 years, were selected. The results of the 51Cr-EDTA slope intercept clearance of the two blood sample method were used as reference. Using the paediatric BACKGROUND AND OBJECTIVES: 51Cr EDTA clearance (CL) from plasma is used to estimate glomerular filtration rate (GFR). We propose that current methods for analysing the raw 51Cr EDTA measurements over-simplifies the disposition of 51Cr EDTA and therefore could produce biased GFR estimates. Individual GFR values from 51Cr-EDTA plasma clearance highly correlated with those from renal clearance (r2 = 0.977, P < 0.0001), but resulted on average about 2.5 mL.min-1.1.73 m-2 higher (66.8 +/- 6.5 mL.min-1.1.73 m-2 (mean +/- SE) versus 64.3 +/- 6.4, P < 0.02). The calculation of 51Cr-EDTA clearance by method I (ClI) was based on a transformation of the biexponential time-activity curve into a monoexponential with identical area below the time-activity curve. The calculation of 51Cr-EDTA clearance by method II (ClII) was based on a close relation between 51Cr-EDTA clearance and the reciprocal apparent volume of distribution normalized with respect to body surface area.

Methods: Two groups of patients with 51Cr-EDTA clearance (Cl) between 16 and 172 ml/min were studied. In Group I (n = 46), reference Cl was determined as a multiplasma sample, single-injection method (ClSM). Sixteen blood samples were drawn from 0 until 5 hr after a single intravenous injection of 51Cr-EDTA. In Group II (n = 1046), reference Cl was

Part II: Empirically determined relationships Both 99m Tc-DTPA and 51 Cr-EDTA are widely used to determine glomerular filtration rate (GFR), but few direct comparative studies exist. The shortage of 51 Cr-EDTA makes a direct comparison highly relevant. The aim of the study was to investigate if there is any clinically relevant difference between plasma clearance of 99m Tc-DTPA and 51 Cr-EDTA.

Reassessment of a classical single injection 51Cr-EDTA clearance method for determination of renal function in children and adults. Part I: Analytically correct relationship between total and one-pool clearance. Renal clearance of EDTA after single injection was 7.5 ± 1.5 mL min −1 (∼12%) lower than inulin clearance (P < 0.001). Values of creatinine clearances determined by the two analytical methods showed a poor agreement with inulin clearance. 51Cr-EDTA clearance was determined in 50 children from the activity in one plasma sample by means of two methods. The calculation of 51Cr-EDTA clearance by method I (ClI) was based on a transformation of the biexponential time-activity curve into a monoexponential with identical area below the time-activity curve. Estimation of the glomerular filtration rate (GFR) is a useful tool in the evaluation of kidney function in feline medicine.

AIMS: To investigate the agreement of glomerular filtration rate (GFR) determination between 51Cr-ethylenediaminetetraacetic acid (51Cr-EDTA) plasma clearance (GFREDTA) and 99mTc-diethylenetriaminepentaacetic acid (99mTc-DTPA) plasma clearance (GFRDTPA), the Gates 99mTc-DTPA renographic method (GFRGates) and the serum creatinine Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI, GFRSCr) in patients with type 2 diabetes mellitus (T2DM). 51 Cr‐EDTA clearance was measured with the standard bolus injection technique and glomerular filtration rate (GFR) was calculated by the single‐sample method described by Jacobsson. Mannitol, 0·25 g kg −1 body weight (150 mg ml −1 ), was infused for 4–14 min and blood samples taken at 1‐, 2‐, 3‐ and 4‐h ( n = 24) or 2‐, 3‐, 3·5‐ and 4‐h after infusion ( n = 17). AIM: The aim of this study was to evaluate the efficacy of 51Cr-EDTA clearance to tailor the carboplatin dose in two different therapeutic regimens of advanced epithelial ovarian cancer.

Sixteen blood samples were drawn from 0 until 5 hr after a single intravenous injection of 51Cr-EDTA. In Group II (n = 1046), reference Cl was The reliability of a determination of the total [51Cr]EDTA plasma clearance (E) (and with it the glomerular filtration rate), by a simplified single injection method (injected dose: 4.5 muCi per kg b.w.) using capillary blood samples (0.2 ml), was investigated in twenty children. From a large database of 51Cr-ethylenediaminetetraacetic acid (51Cr-EDTA) renal clearance determinations using the two blood sample method, 598 patients, aged 1 week to 90 years, were selected. The results of the 51Cr-EDTA slope intercept clearance of the two blood sample method were used as reference.
