The use of 91Y, 51Cr-EDTA, and 141Cr as nonabosrbed reference substances in the gastrointestinal tract of the chick was examined. In single oral dose experiments, more than 95% of the isotopes administered was recovered from the gastrointestinal tract 3 hours after dosing. 51Cr was higher in blood t …

RATIONALE AND OBJECTIVES: To improve the measurement of the glomerular filtration rate (GFR), we determined the extrarenal plasma clearance of the GFR markers iohexol, chromium-51-ethylenediaminetetraacetic acid (51Cr-EDTA), and inulin using 11 anephric pigs. Clearance of iohexol, 51Cr-EDTA and endogenous creatinine for determination of glomerular filtration rate in pigs with reduced renal function: a comparison between different clearance techniques. Scandinavian Journal of Clinical & Laboratory Investigation, 57(3), 241-252. CONCLUSIONS: Iohexol and 51Cr-EDTA are comparable as GFR markers for multiple-point clearance measurements. 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. Plasma clearance of 51Cr‐EDTA (51Cr‐EDTA‐Cl) is an alternative method to evaluate glomerular filtration rate (GFR).

Plasma clearance of 51Cr‐EDTA (51Cr‐EDTA‐Cl) is an alternative method to evaluate glomerular filtration rate (GFR). This study aimed to investigate the concordance between 51Cr‐EDTA‐Cl and renal inulin clearance (In‐Cl) in renal transplant recipients as well to determine the repeatability of 51Cr‐EDTA‐Cl in kidney donors.

20 May 2015 2576 Background: 51Cr-GFR is considered a gold standard of GFR formula ( IDMS-GFR), with measured GFR using 51Cr-EDTA (51Cr-GFR).

Ur erhållna tidsförskjutningen beräknades för 51Cr-EDTA värden på  In most cases GFR is estimated based on plasma creatinine, but cystatin C, creatinine clearance (with urine collection), iohexol clearance and 51Cr-EDTA  av S VILHELMSDOTTER — varande tillförsel av johexol eller krom-EDTA (51Cr-EDTA).
