BIOAGE: Biological Age Test

BIOAGE measures your biological age (how old your body truly is at the cellular level) and compares it to your chronological age, giving you a clear longevity score you can track over time.

Your chronological age counts the years since birth. Your biological age reflects how your body has actually aged based on cellular and molecular markers, and it can be younger or older than your chronological age.

BIOAGE gives you a focused biological age score and is an accessible entry point to longevity testing. EPISPAN is a more advanced epigenetic test that also breaks down the aging of up to 11 separate organ systems and your pace of aging.

BIOAGE uses a simple blood or saliva sample collected at the clinic, with no special preparation needed.

Results are typically available within 4 to 6 weeks, followed by a physician-led review session.

Your results are reviewed by Dr. Sarassawadee Suwanjinda (Petch), our Founder and longevity physician, who builds a personalized action plan around your data.

Four methods are used in practice. Epigenetic clocks read DNA methylation patterns across thousands of sites and are currently the best-validated approach. Telomere length analysis measures the protective caps on your chromosomes. Blood biomarker panels combine markers such as inflammation, glucose regulation and organ function into a composite score. Functional assessments measure grip strength, VO2 max and similar physical capacity. BIOAGE uses a biomarker-based score from a blood or saliva sample; EPISPAN uses epigenetic methylation analysis.

They measure nothing. A free calculator asks about your diet, exercise, smoking and sleep, then applies population averages to your answers — it is a structured questionnaire, not a test. It can be useful for thinking about your habits, but two people giving identical answers can have very different cellular ages and the calculator cannot tell them apart. A laboratory test reads your own biology instead of a population average.

No. Metabolic age comes from body-composition scales and compares your basal metabolic rate to population averages for your age group, so it reflects body composition alone. Biological age is measured from cellular and molecular markers and covers considerably more than metabolism.

At Healthi Life, BIOAGE is ฿15,000 and includes the physician review session. EPISPAN, the advanced epigenetic test, is ฿35,000. Both prices are indicative and confirmed at your physician consultation.

Every 12 months for most people. These markers move slowly, and retesting sooner mostly measures assay variation rather than a real change in your biology. Retesting at 6 months can make sense when a substantial intervention has been started and your physician wants to track its effect.

Research associates a lower biological age score with regular physical activity, sleep quality, nutrition, stress management and reduced exposure to tobacco and alcohol — the same factors that support healthy aging generally. Results vary between individuals and no outcome can be promised. Your physician uses the score as the starting point for a plan, and the follow-up test is what tells you whether that plan moved anything.
