Discover whether your body is ageing faster or slower than your calendar says.
Two people can be 42 years old on paper but have bodies ageing at very different rates. Biological age tells you which one you are.
If your biological age is lower than your chronological age, your lifestyle is working. If it's higher, your report shows exactly which markers to fix - and by how much.
The PhenoAge algorithm follows a three-step process validated against mortality data from the National Health and Nutrition Examination Survey (NHANES):
Step 1: Linear mortality score
xb = -19.9067 + Σ(coefficient × biomarker_value)
Step 2: 10-year Gompertz mortality probability
mortality = 1 − exp(−exp(xb) × (exp(120γ) − 1) / γ)
Step 3: Convert to biological age
PhenoAge = 141.50 + ln(−0.00553 × ln(1 − mortality)) / 0.090165
Levine et al., 2018. Validated against NHANES mortality data.
Your report doesn't just show a single number. For each of the 9 biomarkers, we calculate a counterfactual delta - how many years older or younger you'd be if that single marker were at its optimal value. This tells you exactly which biomarkers are aging you fastest and where to focus.
Indian labs commonly report RDW-SD instead of RDW-CV. Our algorithm automatically derives RDW-CV from RDW-SD and MCV, so PhenoAge works with reports from any Indian diagnostic lab - SRL, Thyrocare, Metropolis, Dr. Lal PathLabs, and others.
A biological age test uses blood biomarkers to estimate how fast your body is ageing compared to your chronological age. Smart Health Report uses the PhenoAge algorithm (Levine et al., 2018), which analyses 9 biomarkers — albumin, creatinine, glucose, CRP, lymphocyte %, MCV, RDW-CV, ALP, and WBC — to compute your true biological age.
PhenoAge is a validated biological age algorithm developed by Dr. Morgan Levine at Yale, published in Aging Cell (2018). It converts blood biomarker values into a 10-year mortality probability, then maps that probability to a biological age. It was validated against 10,000+ participants in the NHANES dataset.
Yes. Since PhenoAge is driven by blood biomarkers, improving those markers through diet, exercise, sleep, and supplements will lower your biological age over time. Your report shows which specific markers are ageing you fastest so you know exactly where to focus.
Most do. Indian labs often report RDW-SD instead of RDW-CV, but Smart Health Report automatically converts RDW-SD to RDW-CV. PhenoAge works with reports from Thyrocare, Dr. Lal PathLabs, Metropolis, SRL, Healthians, Redcliffe, and all major Indian diagnostic labs.
