However, iohexol Njurens clearance är normalt sett 0 - 500 ml/min men om en markörsubstans utsöndras endast via glomerulära filtrationshastigheten (GFR) så är njurens clearance i dessa fall 80 - 120 ml/min. För att lättare förstå begreppet renal clearance kan man ta ett exempel med kreatininclearance. Doseringen av läkemedel som främst utsöndras via njurarna (renal elimination) bör vid nedsatt njurfunktion anpassas så att läkemedelskoncentrationen inte blir för hög och allvarliga biverkningar drabbar patienten.

Serum iohexol concentration for each serum sample was measured using deltaDOT Ltd.'s previously validated high‐performance capillary electrophoresis method. 24 Glomerular filtration rate was estimated from the iohexol clearance data by application of a compartmental model and a dog‐specific correction formula, 13 normalized to body weight

Iohexol: studies comparing iohexol with inulin clearance To the best of our knowledge, only two studies have compared urinary clearances of iohexol and inulin [ 100 , 101 ] (Table 2 ). Both showed excellent correlation between the two methods, but the statistical tools used in the original publications were limited and re-analysed data demonstrated less impressive concordance [ 3 ].

METHODS: The GFR of 96 children with different stages of chronic kidney disease (CKD) (median age 9.2 years, range 3 months to 17.5 years) was determined using the iohexol plasma clearance, with blood sampling at seven time points within 5 h (GFR7p) as the reference method.
