Cystatin C as a measure of renal function overcomes the limitations of using the creatinine level. This is due to its concentration not being influenced by age, sex, or body mass
Sensitivity: The lowest level of human cystatin c that can be detected by this assay is 0.23 ng/ml.
Specificity: The antibodies used in this assay are specific to human cystatin c and do not cross-react with mouse and rat cystatin c, and other cytokine or hormone molecules.
Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested 12 times on one plate.
