Kreatinin fortfarande den vanligaste njurfunktionsanalysen. Undersökning av praxis i Sverige
Sammanfattning
Markers of renal function (glomerular filtration rate; GFR) are frequently used. In most cases GFR is estimated based on plasma creatinine, but cystatin C, creatinine clearance (with urine collection), iohexol clearance and 51Cr-EDTA clearance are also used. A questionnaire was sent to representatives for clinical chemistry laboratories in Sweden to collect information regarding the use of these markers during the years 2006 2009. The aim was to compare the use in different parts of Sweden and how it has changed over time. The overall use of markers of renal function, including creatinine, continues to increase on a national level, with the exception for endogenous creatinine clearance and 51Cr-EDTA clearance. Creatinine, the most frequently used marker, continues to grow in numbers. 5,6 million creatinine analyses and about two hundred thousand cystatin C analyses were performed during year 2009. There were considerable variations between counties in the use of the studied markers.
