Biological aging
Proteomic aging clock
Research-stage biomarkerProteomicsBloodmodel-specific
An aging estimate derived from patterns of circulating proteins.
What it measures
A multivariate protein signature trained against age or aging-related outcomes.
Why it matters
Proteins can capture disease and physiological signals relevant to aging and risk prediction.
How to interpret it
Interpret only within the assay platform and model validation population.
Important limitations
Platforms and models differ; generalizability and clinical utility remain active research questions.
Evidence status
Research-stage biomarker
Rapidly developing aging-biomarker class with promising predictive applications.
