Composite biomarker predictors, which combine multiple clinical and biochemical markers (e.g., CRP, creatinine, blood pressure), are effective biological age predictors that correlate with mortality, physical function, and cognitive decline, often outperforming single biomarkers like telomere length.

Composite biomarker scores, which combine multiple blood tests and clinical measures (like blood pressure and cholesterol), are powerful tools for assessing biological age. They often predict health outcomes and mortality better than single markers. While more complex to obtain, they provide a more comprehensive view of your systemic health than a single test, helping to identify risks that might be missed by looking at one factor alone.

ModerateSupportsMEDIUM confidence
Health outcomes such as IQ and physical function measured in the Dunedin participants seem to be best predicted by the composite biomarker age, then by DNAmAge and not at all by telomere length.

Why this rating

Validated in large cohorts (NHANES III, Dunedin), but models vary between studies (Levine vs. Sebastiani), limiting direct comparison.
