kidney disease test kit / cystatin C / serum / plasma
for kidney disease
latex agglutination, immunoturbidimetric
Cystatin C is a basic protease inhibitor with a low molecular mass (13 Kda). It is produced at a constant rate in all nucleated cells and appears in human plasma and serum.
Clinical studies have shown that Cystatin C is more accurate than serum creatinine and the Cockcroft-Gault estimation of creatinine clearance and is more reliable than the 24-hour creatinine clearance.
There is a growing body of evidence that suggests that Cystatin C can be used to detect kidney disease at earlier stages than serum creatinine which may help facilitate prevention efforts in the elderly and those with diabetes, hypertension, or cardiovascular disease.
