Cystatin C

Product catalog summary
Analytical Procedure
The document describes the use of PETIA (Particle-Enhanced Turbidimetric ImmunoAssay) technology for measuring Cystatin C in serum and plasma. This method involves latex particles coated with antibodies that react with Cystatin C, causing an agglutination reaction. The change in absorbance is proportional to the Cystatin C concentration.

Clinical Advantages
The procedure is standardized against ERM-DA-471/IFCC and is commutable with major clinical studies. Reference intervals are based on a study of 259 adults. The eGFR formula is validated on 4258 adults and 702 children, providing a reliable measure of kidney function.

Analytical Advantages
The reagent is ready to use, with an 18-month stability from manufacture and 45 days onboard stability. It has a sensitivity of 0.05 mg/L and a measuring range up to 10.0 mg/L. The method is resistant to endogenous interference and has been evaluated for drug interference.

Product Information
The document lists product references for Cystatin C reagents, calibrators, and control sets, along with contact information for Sentinel CH. SpA in Milan, Italy.

The method The use of PETIA (Particle-Enhanced Turbidimetric ImmunoAssay) technology allows for an accurate and reproducible quantitative measurement of Cystatin C in serum and plasma. The latex particles coated with antibodies against human Cystatin C, when mixed with a sample containing human Cystatin C, develop an agglutination reaction with a variation in absorbance due to the formation of an immunocomplex which is proportional to the concentration of human Cystatin C present in the sample.
