Focus Testing model
What It Covers
  • An epigenetic clock from a blood or saliva sample
  • A blood-marker composite age from standard labs
  • A proteomic or organ-specific age in newer products
  • A pace-of-aging score
  • Repeat testing at six or twelve months
  • A dashboard tying the score to lifestyle advice
Typical Cost $100 to $1,000 per test
Evidence Level Early: clocks predict risk across populations, individual results vary between tests and between clocks, and no trial shows that treating to a clock target improves outcomes
Regulatory Status Mostly laboratory-developed or consumer wellness tests, not FDA-cleared diagnostics
Watchouts
  • No confidence range or test-retest variability reported
  • A score attributed to a product the seller also markets
  • The clock switched between baseline and follow-up
  • The result framed as a diagnosis
Questions To Ask
  • Which clock is this and what population was it trained on?
  • How much does the result move on retest with no changes?
  • Will the same clock be used at follow-up?
  • What would a five-year drop in this number mean clinically?
