🔬 Biological Age Markers: Which Tests Reflect Aging Rate
How to measure biological age with tests
Biological age is an assessment of body condition relative to the norm, which differs from chronological age. Let's look at which tests reflect the rate of aging.
What is biological age
Biological age reflects the functional state of the body, which can differ from chronological age. It is influenced by genetics, lifestyle and inflammation.
- Assessment of body condition.
- Differs from chronological.
- Lifestyle matters.
- Can be measured.
Telomere length
Telomeres are protective regions at the ends of chromosomes. They shorten with each cell division and are a classic marker of cellular aging.
- End of chromosomes.
- Shorten with division.
- Marker of cellular aging.
- Measured in blood.
Epigenetic clocks
Epigenetic clocks (e.g., Horvath) estimate age by DNA methylation. This is one of the most accurate markers of biological age.
- DNA methylation.
- Accurate age estimate.
- Panels like Horvath.
- Expensive tests.
Lab markers
| Marker | What it reflects |
|---|---|
| HbA1c | Metabolic aging |
| Lipid profile | Cardiovascular health |
| Ferritin | Iron stores |
| Vitamin D | Immunity and bones |
Inflammation markers
Chronic inflammation accelerates aging. Key markers are hsCRP, fibrinogen, interleukins.
- hsCRP — systemic inflammation.
- Fibrinogen.
- Interleukin-6.
- Oxidative stress.
Which tests to take
- Telomere length.
- Epigenetic clocks.
- hsCRP, HbA1c.
- Lipid profile, ferritin.
- Vitamin D, B12.
Practice
- Start with basic tests (hsCRP, HbA1c, lipids).
- Repeat once a year.
- Adjust lifestyle.
- Consult a doctor.
- Epigenetic clocks — optional.
What is biological age?
An assessment of body condition relative to the norm, which differs from chronological age.
What are telomeres?
Protective regions at chromosome ends that shorten with each cell division.
What are epigenetic clocks?
A method to estimate age by DNA methylation, e.g., Horvath.
Which tests to take for aging?
Telomeres, hsCRP, HbA1c, lipids, ferritin, vitamin D.
What is hsCRP?
High-sensitivity C-reactive protein, a marker of systemic inflammation.
Are bioage tests accurate?
Epigenetic clocks are accurate but need interpretation.
Can aging be slowed?
Yes, through lifestyle: diet, sleep, movement, reducing inflammation.
How much does a bioage test cost?
Epigenetic tests are expensive; basic tests are affordable.
What affects bioage?
Genetics, diet, sleep, stress, inflammation, activity.
Is a doctor needed?
Yes, for correct interpretation.
