The calculation of 51 Cr‐EDTA clearance by method I (Cl I) 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 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.

The calculation of 51 Cr‐EDTA clearance by method I (Cl I) was based on a transformation of the biexponential time‐activity curve into a monoexponential with identical area below the time‐activity curve.

It was demonstrated that the two methods were closely related. 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. Since "Cr-EDTA is not bound by plasma proteins and is Two groups of patients with 51Cr-EDTA clearance (Cl) between 16 and 172 ml/min were studied.
• In comparative studies patients with diabetes are under-represented or missing. • A close agreement is shown between 51 Cr-EDTA and 99m Tc-DTPA plasma clearance. • 99m Tc-DTPA plasma clearance can replace 51 Cr-EDTA in patients with type 2 diabetes. • 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].

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).

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

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 …

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 51 Cr‐EDTA (range of clearance: 8–183 mL/min/1.73 m 2). 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.

The single-sample method for GFR >40 ml/min can be used with a high accuracy. The precision and accuracy of X-ray fluorescence analysis of low concentrations of iohexol were less than those of HPLC. Renal clearance of creatinine was significantly lower than renal clearance of iohexol (p = 0.0019) and 51Cr-EDTA (p = 0.0001). There were no significant differences between the renal clearances (Clren adv) of iohexol and 51Cr-EDTA or between their plasma clearances (ClAUC-3comp). In 74 adult patients suffering from various renal diseases, the total [51 Cr]EDTA plasma clearance (Cl) was compared to the [51 Cr]EDTA clearance obtained on assuming a one-pool system (Cl 1).Cl 1 always exceeded Cl, and the relative difference increased with increasing clearance values. An equation for correction is given. The method for determining Cl 1 is very simple and suitable for IgAN regularly with 51Cr-EDTA clearance as an accurate method of GFR determination.
