Fig. 2From: HPLC estimation of iothalamate to measure glomerular filtration rate in humansPlasma concentrations of iothalamate in 20 subjects after a single intravenous bolus injection of 1.5-mL Conray™ 43. Plasma iothalamate concentrations ranged between 4.32 and 16.36 μg/mL in the 20 subjects, error bars represents standard error of mean (SEM)Back to article page
