Parameter
| Biomarker | Cr | Full name | Creatinine | Molecular Type | Metabolites |
|---|---|---|---|---|---|
| Molecular Formula | C₄H₇N₃O | Molecular Weight | 113.12 g/mol | Core Functional Dimensions | Renal function assessment, disease staging |
| Disease | Chronic Kidney Disease (CKD) | Disease Subtypes | / | ||
| Organ | Kidney | Test Sample / Technology Platform | Blood ( routine biochemical tests ) | ||
| Pathobiological Mechanisms | Muscle metabolic waste is excreted through glomerular filtration, and elevated levels reflect reduced GFR. | ||||
| Clinical Availability Status | Clinical routine application | ||||
| Notes and Dynamics | Affected by muscle mass and diet, it is only suitable for the evaluation of middle and late CKD, and cannot identify early renal function injury. | ||||
