Science and method
A method you can inspect.
How Vector estimates biological age, which reference intervals it publishes and why, and how pathology reports are processed — stated plainly enough to argue with.
Method
Biological age methodology
The published foundation, the nine core inputs, the Australian unit adaptation, the secondary layers, and where the estimate stops being meaningful.

Reference ranges
Which Australian intervals are nationally harmonised — currently 17 of them — and why the rest belong to your laboratory.

Pathology processing
On-device extraction, the review step, the secure fallback for difficult formats, and what happens to a source file afterwards.
Read the pageThe foundation
Published research, adapted for Australian reports.
Vector's blood biomarker layer builds on the Levine et al. (2018) PhenoAge model — a peer-reviewed, widely cited biological age construct — adapted for the units printed on Australian pathology reports and standardised against an age- and sex-matched population so young adults are not systematically flattered.

Every biomarker Vector tracks has a page stating what it measures, its unit, and whether Australia has a harmonised interval for it.
