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. 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.

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).

The method used in calculating GFR from a single-sample has been described previously (Groth & Aasted, 1984). Standards were made for the determination of the injected dose of 51 Cr-EDTA . The 51 Cr-EDTA blood samples were counted in a well counter 3 days later to allow for sufficient decay of 99m Tc. All GFR results were expressed as ml min )1 .

Written by Jasna Trbojevic-Stankovic Reviewed by Pierre Delanaye A method that allows direct measurement of the baseline and post-captopril glomerular filtration rate using chromium-51 labeled ethylenediamine tetraacetic acid ( The method requires an intravenous injection and blood samples at 2 and 4 hours; urine samples are 51Cr EDTA clearance (slope)ml/min/l.73m2S.A.
