Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The aim of this calibration study is the development of an empirical algorithm for calculation of the ECFV using VdIOT, that includes correction for the systematic error due to extrarenal clearance of 125I-iothalamate. To this purpose, the main study parameter is correlation of the distribution volumes of of 125I-iothalamate and Bromide in subjects with a GFR | — |
Secondary
| Measure | Time frame |
|---|---|
| • Urinary clearance of 125I-iothalamate within 24 and 48 hours after administration in subjects with a GFR | — |
