Comparative evaluation of iohexol and inulin clearance for glomerular filtration rate determinations.


We evaluated iohexol as a filtration marker in 150 children. The clearance of iohexol was compared with that of inulin or with a formula clearance. The single-sample clearance of iohexol showed a good correlation with the clearance of inulin (r = 0.834). The clearance of iohexol correlated well (r = 0.672) with the formula clearance. The optimal blood… (More)
