Clinical biomarkerRenal functionBloodmL/min/1.73m²
An estimated measure of kidney filtration.
What it measures
Estimated glomerular filtration based on creatinine and/or cystatin C equations.
Why it matters
Central to clinical assessment and staging of chronic kidney disease.
How to interpret it
Interpret trends, albuminuria and clinical context rather than a single number alone.
Important limitations
Creatinine-based estimates are influenced by muscle mass and other non-renal factors.
Evidence status
Clinical biomarker
Established clinical kidney-function measure strongly relevant to health risk.
