TOP 5 Biomarkers For Longevity
| Biomarker | Relevance to Longevity |
|---|---|
| Glucose Level HbA1c | Glycated hemoglobin (HbA1c) levels reflect average blood glucose concentrations over the previous three months. Higher levels are associated with an increased risk of age-related diseases such as diabetes and cardiovascular disease. |
| Inflammatory markers, especially cardiovascular like CRP should be low | Chronic inflammation is linked to many diseases of aging. C-reactive protein (CRP) is a marker of inflammation, and high levels may predict cardiovascular events and mortality. |
| Cholesterol markers including Lipoprotein(a) | Cholesterol levels, particularly low-density lipoprotein (LDL) and lipoprotein(a), are predictors of cardiovascular health. Elevated levels are associated with an increased risk of atherosclerosis and heart disease. |
| Hormone levels (testosterone) | Hormones like testosterone can influence muscle mass, bone density, and overall metabolic health. Low levels in men have been associated with increased morbidity and mortality. |
| Albumin | Albumin levels can indicate nutritional status and organ function. Low albumin may be a marker for poor health outcomes and increased risk of death. |

The chronological and the biological age of individuals can differ remarkably, and there is a lack of reliable biomarkers to monitor the consequences of aging. In this review we give an overview of commonly mentioned and frequently used potential aging-related biomarkers. We were interested in biomarkers of aging in general and in biomarkers related to cellular senescence in particular. To answer the question whether a biological feature is relevant as a potential biomarker of aging or senescence in the scientific community we used the PICO strategy known from evidence-based medicine. We introduced two scoring systems, aimed at reflecting biomarker relevance and measurement effort, which can be used to support study designs in both clinical and research settings.
