Cystatin C detection reagent (immunofluorescence chromatography)
(CysC)
CysC overview
Cysteinase proteinase inhibitor (CPI) is named cystatin C. Cystatin
C in circulation is removed only through glomerular filtration,
which is an endogenous marker reflecting the change of glomerular
filtration rate, and reabsorbed in the proximal convoluted tubules,
but is metabolized and decomposed completely after reabsorption,
and does not return to blood. Therefore, the concentration of
cystatin C in the blood is determined by glomerular filtration
rate, and does not depend on any external factors, such as gender,
age and diet, It is an ideal endogenous marker reflecting the
change of glomerular filtration rate.
CysC performance index
Detection range | sample size | Sample type | Test time |
0.2~8mg/L | 10μl | Whole blood / serum / plasma | 15min |
Clinical significance of CysC
- The most ideal endogenous marker for GFR reaction
- Early diagnosis and monitoring of renal diseases
- Renal function assessment of AKI high risk population
- The detection of renal function in the process of chronic disease
