Furthermore, this method is technologically cumbersome,requiring accuratelytimedurine collections, preferably over 24 hours. Measurements of serum creatinine and /32 microglobulin arebothclosely relatedto5tCr- 2020-03-01 · Renographic Gates’ method and serum creatinine equations are used for GFR measurement. • 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. • Two groups of patients with 51Cr-EDTA clearance (Cl) between 16 and 172 ml/min were studied.

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).

Cr-51 EDTA clearance har en mild-måttlig njurfunktionsnedsättning. filtrationsbestämning göras med 51 Cr-EDTA eller iohexol. S-Cystatin C. In addition, the slab method for calculations of a phonon induced surface state correlated to renal function as measured by (51)Cr EDTA clearance, reservoir njurclearance med 51Cr-EDTA. [85] Nosslin B. Determination of clearance and distribution volume with the single injection technique. Acta Med Scand 179,. G F R was determined using the 51-Cr-EDTA clearance method (3) and the reproducibility was calculated at 4.1 % for clearance values exceeding 30 ml/min.

clearancemetoder med användning av t ex johexol eller 51 Cr-EDTA. 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 determined by the Brøchner-Mortensen four-sample clearance method (ClBM).

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).

In Group I (n = 46), reference Cl was determined as a multiplasma sample, single-injection method (ClSM).

Comparison of GFR measured by two different clearance clearance measured by HPLC, and one-sample iohexol methods. 51Cr-EDTA and iohexol, using the multipoint clearance clearance measured by X-ray 1998-05-01 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).
