Cystatin C (CysC) is an endogenously expressed, non-glycosylated protein known as a sensitive biomarker for early detection of kidney failure. Beside its obvious advantages over creatinine in estimating the glomerular filtration rate, it has not yet found its way in clinical routine. One major reason for this was the lack of a suitable standardization process, which changed in 2010 with the availability of the certified reference material, ERM-DA471/IFCC. DiaSys achieved excellent results in a recent multicentre study with its Cystatin C FS assay with major advantages over competitors. The results showed that among all tested immunoturbidimetric CysC assays, only the DiaSys test met the performance criteria at the four relevant concentrations. Cystatin C FS is a particle-enhanced immunoturbidimetric test featuring outstanding analytical sensitivity, high prozone security and excellent onboard/calibration stability.
