In elderly CKD patients, measurement of iohexol clearance up to 5 h leads to a clinically relevant overestimation of GFR compared with 24-h measurement. In clinical care, this effect should be bore in mind especially for patients with considerably reduced GFR levels. A new correction formula has been developed to predict mGFR 1440 from mGFR 300
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. Median GFR7p was 65.9 (range 6.3-153) mL/min/1.73 m2. GFR BM =0.990778× Cl 1 −0.001218× Cl 12, where Cl 1 is the plasma clearance calculated according to the one-compartment model. One-compartment plasma clearance of iohexol can be determined by using different sampling protocols in the slow compartment phase. Results: Mean ± SD iohexol clearance estimated via multisample and corrected slope-intercept methods was 2.16 ± 0.35 mL/min/kg and 2.14 ± 0.34 mL/min/kg, respectively.

Figure 1 (A) Relationship between the clearance of iohexol (Cio) slope and clearance of inulin (Cin). The dashed line indicates the line of identity and the straight line indicates the regression line with its 95% confidence limits (dotted lines, 0.7998-1.0002).
Thus, if a calibration discrepancy between the analytical method and the dosing protocol exists, this bias will be directly reflected in the calculated GFR measurement. Objective—To develop a formula for correcting slope-intercept plasma iohexol clearance in cats and to compare clearance of total iohexol (TIox), endo-iohexol (EnIox), and exo-iohexol (ExIox). Animals—20 client-owned, healthy adult and geriatric cats.
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 ).

Objective-To develop a formula for correcting slope-intercept plasma iohexol clearance in cats and to compare clearance of total iohexol (Tlox), endo-iohexol (Enlox), and exo-iohexol (Exlox). Animals-20 client-owned, healthy adult and geriatric cats. Procedures-Plasma clearance of Tlox was determined via multisample and slope-intercept methods.
Objectives The one-compartment iohexol plasma clearance has been proposed as a reliable alternative to renal inulin clearance. However, this method's performance depends on the formula used to calculate glomerular filtration rate (GFR).
