Background. The aim of the present study was to compare the most commonly used GFR markers for clearance measurements, 51Cr-EDTA and iohexol, using two different methods for iohexol analysis, HPLC and X-ray fluorescence, referring both 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. 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 [51 Cr]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 2009-01-01 1997-10-01 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).

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. …

The GFR may show a significant decline, with a serum 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).
