Design outcomes

Primary

Measure	Time frame
Following referencetest is applied to every participant as the primairy parameter. · Inutest single-shot method, to measure sinistrin clearance, in ml/min. Next methods are secondary parameters and will be compared with the reference method: · Cockcroft-Gault formula in ml/min. · MDRD formula in ml/min/173m² • MCQ-formula in ml/min • Virga-formula in ml/min • Jelliffe-formula in ml/min • Salazar-Corcoran-formula in ml/min • Martin-formula in ml/min • Wright-formula in ml/min • Larsson-formula in ml/min • Hoek-formula in ml/min · Creatinine clearance estimation form 2-hour urine sample, in ml/min. · Cystatine C plasma concentration, in mg/l To estimate GFR with the formulas, following variables must be collected : · Serum creatinine concentration · Serum ureum concentration · Serum albumin concentration · Serum Cystatine C concentration · Gender · Race · Date of birth · Body Mass Index (BMI)	—
