NCT01092260

Brief Summary

The purpose of this study is to validate a feasible, safe and reliable iohexol plasma clearance method in routine monitoring of the renal function (GFR) in children. Different parameters of renal function will be compared to the gold standard multiple sample points procedure of iohexol clearance.
