Cystatin C Detection Reagent (Immunofluorescence Chromatography)
(CysC) Performance Index
CysC overview
The cysteine proteinase inhibitor (CPI) is known as cystatin C.
Cycle in inhibition of C is cleared after the glomerular
filtration, only is a kind of endogenous markers to reflect the
actual changes in glomerular filtration rate, and in the proximal
convoluted tubule reuptake, but were completely after heavy
absorption metabolism decomposition, do not return the blood,
therefore, its blood concentration is determined by glomerular
filtration rate, and not dependent on any external factors, such as
gender, age, diet, It is an ideal endogenous marker to reflect 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 ideal endogenous marker for GFR
- Early diagnosis and monitoring of renal diseases
- Renal function assessment in high-risk groups for AKI
Comparison of sensitivity of cystatin C and serum creatinine to
assess GFR
| Cystatin C | Cystatin C |
creatinine | |
GFR(mL/min/1.73m2) | >89 | 60-89 | 30-59 | 15-29 | <15 |
CKD stage | 1 | 2 | 3 | 4 | 5 |
| Renal impairment with normal/elevated GFR | Mild renal insufficiency | Moderate renal insufficiency | Severe renal insufficiency | Stage Renal Disease (ESRD) |
