Your birthday is a
date. Your Delta
is the truth.
Two people born the same year can be a decade apart biologically. Delta Age reads methylation at hundreds of thousands of sites across your genome and resolves them into one number — the gap between how old you are and how old you've actually become.

This is an example integration, not a store
Delta Age is a working reference implementation of the TruDiagnostic public API — built to show how a storefront orders a kit, registers a patient, tracks the sample, and delivers a report end to end. It runs against the TruDiagnostic staging environment and a Stripe sandbox.
You can order, pay with a test card, and follow the whole journey. But nothing here is real: no money changes hands, and no kit will be mailed to you. Every product page below describes the real service so the example reads honestly — the fulfilment behind it is simulated.

One number, built from hundreds of thousands
Methylation is the layer where lifestyle writes itself onto your genome. It changes with how you sleep, eat, train, and recover — which makes it measurable, and makes it movable.
Read the marks
An Illumina EPIC array measures methylation at over 900,000 CpG sites from a single dried blood spot.
Resolve the age
Validated epigenetic clocks translate those marks into a biological age and a pace of aging.
Find the gap
Your Delta is biological minus chronological. Negative is younger. It's the number you can move.
Choose your test
Both run on the same dried blood spot and the same lab pipeline. The difference is how deep the report goes.
Delta Age
Your biological age, measured at the level of DNA methylation.

Measure it. Then move it.
A single reading tells you where you stand. Retesting is how you find out what actually worked.
