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.

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. Patients with advanced epithelial ovarian cancer were treated with first-line carboplatin (AUC = 7, using the 51Cr EDTA [edetic acid] clearance method) and escalating doses of paclitaxel. Thrombocytopenia was mild and was significantly less when the paclitaxel dose was 175 mg/m2 versus 150 mg/m2.

The results of the 51Cr-EDTA slope intercept clearance of the two blood sample method were used as reference. 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. 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 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.

• One systematic review also found strong evidence suggesting that renal clearance of 51Cr-EDTA or iothalamate and plasma clearance of 51Cr-EDTA or iohexol are sufficiently accurate methods to measure GFR [13]. It is Prof. Delanaye’s opinion that iohexol should be regarded as a marker of choice. Background. 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‐intercept clearance), Cl1, is computed. Empirically determined second‐order polynomials of the general form Cl = b⋅Cl1+c⋅Cl12 are usually used to estimate Cl from a measured Cl1. 2021-02-27 Estimation of the glomerular filtration rate (GFR) is a useful tool in the evaluation of kidney function in feline medicine.

Table 3.1.13 Studies evaluating the accuracy of 51Cr-EDTA (radioactively filtration rate) using renal clearance of inulin as the reference method. Author. Year.

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. 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. 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.

as an alternative method to measure GFR and has been used in clinical nephrology since then. In spite of its use for almost four decades, studies comparing In‐Cl and 51 Cr‐EDTA‐Cl have either not included renal transplant recipients [ 12 - 22 ] in their population study or included only a few [ 23 ]. Total plasma clearance of 51Cr‐EDTA, Cl, is widely used as a measure of GFR.

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 a serum 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.
