Designing a Bayesian Model of the Plasma Clearance of Calcium Edetate de Sodium for the Calculation of GFR and Validity Compared to the Renal Clearance of Inulin

There is no medical data for the use of Calcium edetate de sodium as a tracer to assess GFR. Calcium edetate de sodium is a treatment for lead intoxication. The extension of use as a tracer comes from its exclusive elimination by glomerular filtration. Plasma and renal clearance of Calcium edetate de sodium and Inulin will be measured for every included patient during a hospital day care (V1). For transplanted patients, plasma clearance of Calcium edetate de sodium will be repeated within one week (more or less 48hours) during annual medical check-up of renal transplantation.
