Nowadays, creatinine PAP overcomes creatinine Jaffé and with many advantages compared to creatinine PAP, cystatin C has become a more meaningful and highly important assay for renal diagnosis.
In contrast to creatinine PAP it covers the creatinine blind range and by this cystatin C determination is used for detection of early decrease of glomerular filtration rate (GFR).
DiaSys Cystatin C FS is an immunoturbidimetric assay, which can be applied on a broad range of clinical chemistry analyzers. The assay is characterized by an outstanding analytical sensitivity in addition to superior correlation with nephelometry. The assay has excellent onboard and calibration stabilities up to 12 weeks and a high prozone security. The standardized test is essential for reliable renal diagnostics of clinical-chemistry laboratories.
