Common Metrics a Biological Age Test Lists and What They Mean
Telomeres protect chromosome ends and shorten with each cell division. Shorter telomeres estimate higher biological age and increased disease risk. Measured through blood tests using techniques like quantitative PCR.
Common Biomarkers:
- Telomere Length
- DNA Methylation
- Inflammatory Markers
- Metabolic Markers
- Glycan Markers
Methylation patterns affect gene expression and are key age-related biomarkers. Epigenetic clocks, such as Steve Horvath or Hannum, estimate biological age by analyzing these patterns from DNA samples.
Inflammatory markers like C-reactive protein (CRP) and interleukin-6 (IL-6) indicate chronic inflammation, which accelerates aging. High levels suggest a higher biological age and health risks, measured via blood tests.
Glucose, insulin resistance, and lipid profiles (cholesterol, triglycerides) reflect metabolic health and aging rate. These are assessed through standard blood tests.
Glycan patterns change with age and indicate biological age and inflammation. The GlycanAge test analyzes these patterns using advanced glycomics techniques.
DNA Methylation Markers
DNA methylation involves adding a methyl group to cytosine bases in DNA, typically at CpG sites. This serves as an epigenetic marker regulating gene expression by promoting or inhibiting transcription. As we age, these methylation levels change, impacting gene regulation and biological processes associated with aging.
Methylation can silence or activate genes depending on where it occurs. Promoter region methylation generally suppresses genes, while gene body methylation can enhance expression.
Age-related changes in DNA methylation, known as epigenetic drift, indicate biological aging. Measured by DNA methylation clocks, these patterns reveal an individual’s biological age versus chronological age.
Altered methylation patterns contribute to aging-related functional decline. Hypomethylation can cause genomic instability, while hypermethylation can silence tumor suppressor genes, raising cancer risk.

Telomere Length
Telomeres are protective structures that prevent DNA degradation and fusion with other chromosomes. They play a crucial role in maintaining genomic stability during cell division.
Each time a cell divides, telomeres shorten slightly, acting as a biological clock that limits the number of times a cell can divide. This shortening eventually leads to cellular senescence, where cells stop dividing and lose their functionality, contributing to the aging process and the presence of biomarkers associated with aging.
Studies have connected shortened telomere length with conditions such as cardiovascular diseases, diabetes, and certain cancers.
For example, individuals with shorter telomeres have a higher risk of developing coronary artery disease and heart failure. Similarly, shortened telomeres are associated with a greater incidence of diabetes and reduced immune function.
Glycan Structures
Glycosylation, the addition of sugar molecules to proteins and lipids, is crucial for cellular functions such as protein folding, stability, and cell signaling. Scientists have demonstrated that changes in glycan structures can disrupt these processes, indicating the cellular aging process.
Alterations in glycan structures can signify aging and age-related diseases. Emerging research shows that glycans can serve as biomarkers for biological aging. Scientists have demonstrated that specific glycan profiles reflect the cellular aging process, offering valuable insights into health and potential interventions.
Proteomic Markers
Proteomics is the large-scale study of proteins, including their composition, structure, and functions. As individuals age, protein composition and function undergo significant changes. These alterations can affect various cellular processes, such as metabolism, signal transduction, and immune response, contributing to the overall aging process
Specific proteomic markers have been linked to aging. For example, levels of growth differentiation factor 15 (GDF15) increase with age and are associated with chronic diseases and reduced physical function. Other markers like C-reactive protein (CRP) and insulin-like growth factor 1 (IGF-1) also change with age, indicating inflammation and metabolic health.
Metabolite Levels
Metabolomics is the comprehensive study of small molecule metabolites within biological samples. It provides insights into the cellular health and metabolic changes associated with aging. By analyzing the complete set of metabolites, scientists can identify biological markers that reflect the aging process and cellular functions. Metabolomics allows researchers to track changes in metabolite levels, offering a detailed view of how metabolic pathways are altered as we age.
Key metabolites and associated pathways:
- Amino Acids (e.g., glycine, serine, threonine): Involved in protein synthesis and metabolic regulation.
- Lipid Metabolites (e.g., cholesterol, phospholipids): Essential for cell membrane integrity and signaling.
- Glucose and Insulin: Indicators of metabolic health and energy regulation.
Oxidative Stress Markers
Oxidative stress occurs when there is an imbalance between reactive oxygen species (ROS) production and the body’s ability to detoxify these reactive intermediates. Elevated ROS levels cause damage to cellular components, such as DNA, proteins, and lipids, leading to cellular aging and dysfunction. This damage contributes significantly to the aging phenotype.
Common oxidative stress indicators:
- Malondialdehyde (MDA)
- 8-Hydroxy-2′-deoxyguanosine (8-OHdG)
- Protein Carbonyls
Immune Function Indicators
With aging, the immune system undergoes immunosenescence, leading to reduced vaccine efficacy, higher infection rates, and increased autoimmune diseases. These changes can be quantified to assess biological age by evaluating immune system parameters, reflecting overall immune health.
Key immune function indicators commonly used in biological age testing:
- T-Cell Count and Function: Higher and functional T-cells indicate a robust immune system and younger biological age.
- Cytokine Levels: Balanced pro-inflammatory and anti-inflammatory cytokines reflect a healthy immune response and lower biological age.
- Natural Killer (NK) Cell Activity: High NK cell activity is a marker of a strong immune system and younger biological age.
- C-Reactive Protein (CRP) Levels: Lower CRP levels indicate reduced inflammation and a younger biological age.
Thymic Function: Higher thymic output suggests a younger immune system.
Functional Health Metrics
Functional health metrics like muscle strength, lung capacity, and cognitive function are key in biological age tests. Muscle strength, measured through grip tests, indicates overall muscle mass and functionality. Lung capacity, assessed by spirometry, gauges respiratory health and energy levels. Cognitive function, evaluated through memory and attention tests, reflects brain health.
These metrics directly relate to biological age and overall health. Strong muscles indicate vitality, greater lung capacity supports better oxygenation, and high cognitive performance reflects mental sharpness. Together, they provide a comprehensive view of the body’s current biological state, revealing true health status beyond chronological age.
