Biological Age Test Shopping Guide
Humanic Blue’s Longevity365 guide: Biological-age tests share a label while using different samples and calculations. TruAge and Index use DNA patterns, GlycanAge studies sugar structures on immune proteins, and InnerAge2.0 works from ordinary blood markers.
Explore the productsFor readers interested in living longer and better, the first distinction is what a test measures and what its software calculates from the sample.
01 / Our approach
How did we evaluate these products and services?
We compared company-described samples, report contents, membership requirements and availability. An age estimate, a laboratory measurement and a diagnosis answer different questions.
Best Biological Age Tests: evidence and sources02 / The takeaways
What did the source evidence show?
- TruAge uses a blood spot and Index uses saliva, although both analyze DNA methylation.
- GlycanAge includes a specialist consultation and uses a different biological signal.
- InnerAge2.0 can be added to Ultimate or purchased with its own professional blood draw.
What does an age number leave out about the method used to calculate it?
The products and services
What is distinct about each product or service?
The order is not a ranking. The profiles distinguish the sample, report and access route for each named offering.
The matrix compares sample collection and the kind of information returned; it does not rank clinical value.

TruDiagnostic TruAge Test
Service formatHome finger-prick blood spot
TruDiagnostic says TruAge uses DNA methylation—chemical tags on DNA—to estimate biological age, aging speed and ages for eleven organ systems. Current report names include OMICmAge, DunedinPACE and SYMPHONYAge.
The sample is mailed back and results appear in a secure portal. Some report items estimate blood markers or physical performance from DNA patterns; they are not direct blood-chemistry, grip-strength or walking tests. The current name is TruAge Test, at the former COMPLETE web address.

Elysium Index
Service formatHome saliva kit
Elysium says Index uses DNA methylation in a saliva sample to report biological age, cumulative rate of aging and nine system ages, including heart, brain and metabolic systems. The kit is collected at home and results appear in an account report.
The company says Index is not FDA approved and is not intended to diagnose disease or assess disease risk. A system-age label is the company’s calculation, rather than an examination of that organ.
Product 03 / 04
GlycanAge Test
Service formatHome finger-prick kit with consultation
GlycanAge analyzes sugar structures attached to immune proteins in blood. The company says those patterns reflect inflammation-related aging and uses them to calculate a biological-age result and additional glycan indexes.
This is a different method from DNA methylation. The package includes a report and specialist video consultation. An inflammation-related pattern does not identify a particular disease.
Product 04 / 04
InsideTracker InnerAge2.0
Service formatBlood-marker age analysis
InsideTracker says InnerAge2.0 calculates an age-style score from selected blood markers: seventeen for men and thirteen for women. It compares those results with age and biological-sex peers.
It can be bought with a professional lab or mobile draw, or added to an existing Ultimate test. A professional home blood draw differs from collecting a finger-prick sample yourself. This is not a DNA methylation test.
Would a consultation or a particular sample route change the experience of receiving a result?
Reader Questions
A few questions to consider while reading the evidence.
- Which difference would change what you expect to learn from a result?
- What question would still need an answer after the report arrives?
