Allergic and nephrotoxic side effects were not observed. CONCLUSION: Iohexol clearance is a valid method for measuring GFR in patients at any stages of renal failure. Elimination rate and clearance of the contrast media were measured as indices of their dialyzability. RESULTS: After 4 hours of hemodialysis, 78.4+/-6.5% of iohexol and 72.4+/-6.0% ioxaglate were eliminated. Clearance of iohexol was higher than that of ioxaglate at all sampling times. No severe hemodynamic change nor adverse reaction were observed.

Iohexol clearance determinations are now per-formed at numerous hospitals in Sweden. A national quality assurance program, now including 20 different laboratories, was initiated in 1996. All use versions of the HPLC technique. Evaluation of the program shows that the method has a satisfactory performance.

Ett eller flera blodprov tas efter 3–5 timmar, men vid kraftigt sänkt njurfunktion (förväntat värde <20ml/min tas provet dagen efter.

genomfört många förbättringar av njurfunktionsdiagnostiken: plasmaclearance av iohexol som. The renal clearance of iohexol was evaluated as an alternative method for RRF assessment (iohexol-derived RRF) in hemodialysis patients. An intravenous bolus of iohexol (12 ml; 300 mg iodine/ml) was administered to 42 hemodialysis patients following routine HD. Thus, we believe that properly performed plasma iohexol clearance using long sampling time is a suitable technique for estimating residual kidney function in patients receiving hemodialysis. The established method based on urine collection and blood sampling is less suited for everyday clinical practice.

During dialysis the clearances of iohexol and iodixanol were, respectively, 69 ± 16 and 58 ± 11 ml/min/1.73 m2 when calculated from a single-pool model (hemodialysis clearance of CM from plasma).

Conventional quantitation of RRF in hemodialysis (HD) patients is measured by urea clearance and requires a 24-hour urine collection which is often difficult to perform and inaccurate.

Varje dygn filtreras ca 180 liter plasma varav den I de fall Klinisk fysiologi utfört belastning, beräkning och läkarbedömning åt vårdgivare ansvarar Klinisk kemi endast för mätning av S-Iohexol. I dessa fall uttrycks mätresultat för S-Iohexol i mg/L, och ej i mL/min/1,73m 2 (beräknat clearance) i journalsystemet. Iohexol-clearance används för bedömning av njurarnas filtrationsförmåga (GFR). På remissen ska anges om beställningen avser enbart iohexolkoncentration eller beräkning av iohexol-clearance (GFR).
