Parameter
| Biomarker | Cys-C | Full name | Cystatin C | Molecular Type | Protein |
|---|---|---|---|---|---|
| Molecular Formula | / | Molecular Weight | / | Core Functional Dimensions | Diagnosis (early) |
| Disease | Acute Kidney Injury (AKI) | Disease Subtypes | / | ||
| Organ | Kidney | Test Sample / Technology Platform | Serum（immunoassay、ELISA） | ||
| Pathobiological Mechanisms | Glomerular free filtration, unaffected by muscle mass, reflects changes in GFR earlier. | ||||
| Clinical Availability Status | Study test | ||||
| Notes and Dynamics | It is more sensitive than creatinine, and can be combined with creatinine to optimize diagnostic accuracy. There is a lack of ICU population-specific formula. | ||||
