Parameter
| Biomarker | eGFR | Full name | Estimated Glomerular Filtration Rate | Molecular Type | Functional parameter |
|---|---|---|---|---|---|
| Molecular Formula | Molecular Weight | Core Functional Dimensions | Diagnosis, staging and prognosis judgment | ||
| Disease | Chronic Kidney Disease (CKD) | Disease Subtypes | / | ||
| Organ | Kidney | Test Sample / Technology Platform | Serum ( based on biochemical test results + formula calculation ) | ||
| Pathobiological Mechanisms | Through endogenous markers such as creatinine and cystatin C, combined with age, gender and other parameters, calculated by formulas ( such as CKD-EPI, Cockcroft-Gault ), glomerular filtration function is indirectly reflected. | ||||
| Clinical Availability Status | Clinical routine use ( core diagnostic indicators ) | ||||
| Notes and Dynamics | CKD diagnostic criteria : GFR < 60 mL / min / 1.73 m 2 for 3 months ; the new CKD-EPI equation removes ethnic variables and reduces population bias ; it should be combined with the evidence of renal injury ( such as albuminuria ) to make a comprehensive judgment | ||||
