51Cr-EDTA plasma clearance has been demonstrated to be comparable to thus may be considered a secondary standard against which other techniques can

The precision of two different clearance methods as used for routine assessment of the glomerular filtration rate (GFR) was investigated in thirty-one children aged 0.6-14 years: total [51Cr]EDTA plasma clearance (E) determined by a simplified single injection method; and 24 h endogenous creatinine clearance (C). Material and methods. 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).

An equation for correction is given. The method for determining Cl 1 is very simple and suitable for In anaesthetized pigs, clearances of 51 Cr‐EDTA (EDTA) and endogenous creatinine were compared with renal clearance of inulin measured during constant infusion after bolus injection. Creatinine was determined by enzymatic (Kodak Ektachem) as well as conventional (Jaffé) methods. In saline‐loaded pigs, renal clearance of constantly infused EDTA was 97.0 ± 6.7 mL min −1 and identical to This study was undertaken to compare the serum beta2-microglobulin (beta2-m) as a test of renal function with the plasm creatinine and the glomerular filtration rate as estimated by the 24 hour endogenous creatinine clearance and the single injection 51Cr EDTA clearance method. Of the 33 patients with a variety of renal diseases and the four 1984-03-01 2020-03-01 The precision of two different clearance methods as used for routine assessment of the glomerular filtration rate (GFR) was investigated in thirty-one children aged 0.6-14 years: total [51Cr]EDTA plasma clearance (E) determined by a simplified single injection method; and 24 h endogenous creatinine clearance (C). Determination of C twice only succeeded in twenty children because of problems in 2021-02-27 A method is described whereby the plasma clearance of 51Cr‐EDTA is used to estimate the glomerular filtration rate (GFR) in conscious rats. EDTA clearance rates were calculated based on one and two exponential disappearance curves and compared in groups of animals studied under conditions of normal, high and low GFR. Like previously described related methodologies, this technique obviates (1998) Brändström et al.

extraction ratio of 51Cr-EDTA are based on studies in our laboratory of 14 kidneys which had a normal clearance rate of 51Cr-EDTA, normal renograms, and a normal extraction ratio of PAH (Table 2). Results The HbA1 values are given in Table I. Mean SD for the group was 11.8 1.9%. Three patients had an unsatisfactory Significant covariates included CL Cr on 51 Cr EDTA clearance and total weight body on central volume.

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.

EDTA clearance rates were calculated based on one and two exponential disappearance curves and compared in groups of animals studied under conditions of normal, high and low GFR. 1986-01-01 · Pathology (1986), 18, pp. 445-447 COMPARISON OF 51Cr EDTA CLEARANCE WITH FORMULAE IN THE MEASUREMENT OF GLOMERULAR FILTRATION RATE TERENCE J.

Schwartz formulae in A method that allows direct measurement of the baseline and post-captopril glomerular filtration rate using chromium-51 labeled ethylenediamine tetraacetic acid ( The infusion clearance for .sup.51Cr-EDTA obtained as a measure of GFR lower for GFR.sub.51Cr-EDTA than the urinary CrCl method, 7.2% versus 55.0%.

The plasma clearance of 51 Cr-EDTA was set as the reference standard for comparisons because it has been used extensively in Europe and worldwide for many years and currently is being discontinued, whereas there is compelling evidence that this method provides accurate GFR measurements,. 2. 51 Cr-EDTA is the most often used tracer but the x-ray contrast medium iohexol has become popular in recent years. The plasma clearance technique is recommended when a reliable value of GFR is needed, e.g.

Radioaktivt sönderfall genom emission av en alfapartikel är en process som även Till sådana modeller kan även clearance av substansen och Ficks princip kopplas. 51Cr-EDTA är ett sådant liksom det i njurscintigrafi vanliga 99mTcDTPA.

2013-06-15 2010-08-01 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 … 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. A method is described whereby the plasma clearance of 51 Cr‐EDTA is used to estimate the glomerular filtration rate (GFR) in conscious rats.
