Questions worth asking.
What exactly is my "Delta"?
Your biological age minus your chronological age. If you are 41 and your methylation reads like a typical 36.8-year-old, your Delta is −4.2 years. Negative is younger than the calendar; positive is older.
How is the sample collected?
A finger prick you do yourself at home — a few drops of blood onto a collection card. No venous blood draw, no clinic visit, no fasting. It takes about five minutes.
How long until I get results?
Typically three to five weeks from the moment the lab receives your sample. Shipping and lab intake add a little on the front end. Your dashboard tracks every stage, so you always know where things stand.
Why do I have to register my kit?
Registration links the barcode on your collection card to you, and supplies the date of birth, biological sex, and collection date the lab needs to run and validate the analysis. A card that arrives unregistered cannot be matched to a person, so results cannot be released.
Why does the lab need my date of birth and biological sex?
Both are used in quality control. The lab checks that the age predicted from your methylation is plausible against your stated age, and that genetic sex markers match what you reported. A mismatch usually means a sample handling error, and it is caught before a report goes out.
Is there a minimum age?
Yes — you must be 18 or older. The clocks are validated on adults, and results in minors are not interpretable.
Can I actually change my Delta?
Methylation responds to sleep, exercise, diet, alcohol, smoking, and stress, and studies have shown measurable shifts over months rather than years. Nobody can promise you a specific result. What we can do is give you a consistent measurement so you can tell whether what you changed made a difference.
How often should I retest?
Six to twelve months. Shorter than that and you are mostly measuring noise; the meaningful signal is the trend across repeat tests run the same way.
Who runs the lab work?
TruDiagnostic, a CLIA-certified laboratory specializing in epigenetic analysis. Delta Age handles your ordering, registration, and results.
Is this a medical test?
No. It is a laboratory developed test for wellness and research use. It does not diagnose, treat, cure, or prevent disease, and it does not replace advice from your provider. Bring your report to them if you want it interpreted in a clinical context.
What happens to my sample and data?
Your sample is processed for the test you ordered. Your results live in your Delta Age account and are visible only to you.
What if my sample fails quality control?
It happens occasionally — an under-filled collection card is the usual cause. You will see the failure in your dashboard and we will arrange a replacement kit.
