The 51Cr-EDTA test is a valuable clinical tool for screening intestinal diseases in dogs. The test is performed by calculating the percentage of recovery from urine of a PO-ingested dose of 51Cr-EDTA after 6 or 24 hours.

The calculation of 51 Cr‐EDTA clearance by method II (Cl II) was based on a close relation between 51 Cr‐EDTA clearance and the reciprocal apparent volume of distribution normalized with respect to body surface area. It was demonstrated that the two methods were closely related. To test the accuracy of the two methods, the results of Cl I and CI II, were compared to 51 ‐EDTA clearance calculated by means of a standard, multiple plasma sample method (Cl SM).

In Group II (n = 1046), reference Cl was Plasma clearance rate of 51Cr-EDTA provides a precise and convenient technique for measurement of glomerular filtration rate in diabetic humans J Am Soc Nephrol . 1996 Jan;7(1):118-27. 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. 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.

• A close agreement is shown between 51 Cr-EDTA and 99m Tc-DTPA plasma clearance.

Total plasma clearance of 51Cr‐EDTA, Cl, is widely used as a measure of GFR. Commonly, only the final part of the plasma concentration curve is measured, and a one‐pool clearance (slope Reassessment of a classical single injection 51Cr‐EDTA clearance method for determination of renal function in children and adults.

There were no significant differences between the renal clearances (Clren adv) of iohexol and 51Cr-EDTA or between their plasma clearances (ClAUC-3comp). 1998-05-01 IgAN regularly with 51Cr-EDTA clearance as an accurate method of GFR determination. As serum creatinine is a rough method for determination of renal function, it is of no value in differing between normal and slightly decreased GFR. An extensive survey of this subject has been presented by Brod (16]. The GFR may show a significant decline, with If 5'Cr-EDTA clearance is used as the reference method creatinine clearance seems to underestimate GFRin sickle cell disease. Furthermore, this method is technologically cumbersome,requiring accuratelytimedurine collections, preferably over 24 hours.

Cl was determined in 149 subjects (M/F/children: 71/46/32) from a complete plasma concentration curve followed for 4–5 h after injection of 51Cr‐EDTA (range of clearance: 8–183 mL/min/1.73 m2).

mance. The infusion clearance for 51 Cr-EDTA obtained as a measure of GFR (GFR 51Cr-EDTA) was calculated from the formula: GFR (mL/min/1.73m 2) = (51 Cr-EDTA infusion rate × 1.73)/ (arterial 51 Cr-EDTA × body surface area) and compared with the urinary CrCl and the estimated GFR (eGFR) from the three estimating equations.

We propose that current methods for analysing the raw 51Cr EDTA measurements IgAN regularly with 51Cr-EDTA clearance as an accurate method of GFR determination. As serum creatinine is a rough method for determination of renal function, it is of no value in differing between normal and slightly decreased GFR. An extensive survey of this subject has been presented by Brod (16]. The GFR may show a significant decline, with Iohexol and 51Cr-EDTA are comparable as GFR markers for multiple-point clearance measurements. The single-sample method for GFR >40 ml/min can be used with a high accuracy.

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. that the 51Cr-EDTA clearance corresponds very closely with the inulin clearance when estimated by the standard infusion technique, quoting r values of 0.995 and 0.992, respectively. The renal handling of 51Cr-EDTA and inulin would therefore appear to be identical. … At least moderately strong evidence suggests that renal clearance of 51Cr-EDTA or iothalamate and plasma clearance of 51Cr-EDTA or iohexol are sufficiently accurate methods to measure GFR. 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 … 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). 2004-02-01 Multiple sample methodThe plasma clearance of 51 Cr-EDTA for the entire group of cats ranged between 0.4 and 8.7 ml/min/kg when normalised for body weight (mean AE SD, 3.7 AE 2.5 ml/min/kg).The mean AE SD for the normal cats yielded to 2.4 AE 1.3 ml/min/kg. The mean clearance value for the hyperthyroid cats AE SD was 4.3 AE 1.9 ml/min/kg.
